That is my story with my headlight:
Bought a 2020 F250 with 5miles on it. Halogen headlight assembly.
My initial problem was that there was no real difference between low beam and high beam in position where it scattered) and my headlights were blinding other drivers.
Went to a dealership and figured out that the previous owner replaced the halogen light bulbs to LED. Because I used to the bright LED lights, (and checked how it would be with the original halogen bulbs) so decided or (1) replace the halogen headlight assembly to the factory LED headlight assembly, or (2) to buy good quality LED lights. The dealership said they don't recommend the first option, so went with the second one and purchased the Morimoto 2Stroke 3.0 LEDs with the anti-flicker harness (just to be safe.)
Yesterday replaced the previous LEDs and installed the new Morimoto LEDs. I was so happy, I finally saw the difference between low beam and high beam, adjusted them properly and went to drive around the city, enjoying my new lights.
My happiness lasted for like 5 minutes when I noticed I am blinding the drivers in front of me with huge brightness. Pulled over and checked what is going on? My new lights behaved just like the previous (and cheap looking) LEDs. There was no difference between low beam and high beam, just a short switching blinking indicating I did something.
I got an idea and shut off the engine. After I started the engine, I had again the low beam and high beam. After switching to high - low - high - low, the difference between the two was less and less and finally stopped at no difference stage and with huge brightness.
I have no idea what's the issue. I saw many people changed their halogen bulbs to LED without problem.
I bought the OBD-USB cable for Forscan, not sure if that would help anything?
Please advice me, what could be the problem?
Thank you.

A used truck with only 5 miles and the previous owner replaced the headlight bulbs?
There must be a part of the story missing? But to the OP, if you get into FORScan look into the NON AsBuilt or "plain English" side. The spreadsheet that I have printed at the moment doesn't show headlight settings. But I was just into my truck last week with FORScan for some speedometer adjustments and I recall seeing some headlight settings there. Possibly for halogen to LED or ABM Outage settings, I can't remember exactly. I may have FORScan out later to get rid of the horn honk when I lock the truck with fob. If I do, I'll try to get a picture of where my headlight settings are.
Also, adjust the lights once they're working properly. Some useful information here. I have yet to be flashed since I followed some of the tips.
Just be advised that this seems to be a hot button subject here. You'll be hearing from several telling you what you should and should not do with your headlights.
I can't speak to a 2020 but my 17' was pnp and work great. I bought mine from Headlight Revolution. I did aim them down and I no longer get flashed but to be fair I was getting flashed with the halogen bulbs.

I started with Beamtech over 3 years ago and now have Hikari. I think due to the fact that all 4 lights are always on because all 4 contain both high & low beams that people naturally assume high beam when they see it.
I don't think twice anymore when I see 4 headlights coming at me. I just assume it's one of these trucks.
Here are the pics of my headlight settings within the Non AsBuilt portion of the BdyCM (body control module) of FORScan. FWIW, I am not having the problems that the OP is having with no discernible difference between high & low beams. You can use these pics for comparison to your own settings, but I would suggest checking in with someone like ZooDad who knows what he's doing in FORScan. My settings may not translate to success for the OP.
I'm not the greatest at backing up a module in case something goes wrong. So at the very least write down the things that you changed and note the original settings in case you need to go back.
I can't speak about the GTR bulbs that you're considering. But after getting the wrong bulbs from more than one place for front switchback turn signals, I found GTR. I bought directly from them, not a 3rd party. Sometimes you save that way, sometimes not. But the bulbs snapped in securely when no others did. So my experience with GTR so far has been good.
Thank you for all the replies. I went down to a shop and asked them what they think the problem is and they said I would need a resistor.
Got the Forscan work tonight, looking into it if I can find anything that would work.
When it works, it is not blinding anyone with the proper headlight adjustment, but after a while it goes back just like no adjustment has been made.

Not street legal? Sh...
I've heard of resistors for switching to LED signal lights to stop hyper flash in the cluster, but I haven't seen anyone post that they had to do it for headlights.
Maybe a chance to learn something new. Let us know how things turn out. You never know when someone else will come along and need a solution.
Those GTRs aren’t DOT compliant either. I don’t believe you’ll find any replacement LED bulbs (for headlight use) that are.
Here's an example of some misinformation I found for the Hikari's that I have: I looked under the customer questions that were answered in Amazon and someone said they were legal.
When I did a closer examination at the bottom of the product page, here's a couple of items I copy/pasted directly -
"All LED bulbs from all brands, regardless of marketing claims, are restricted from headlamp usage under current federal regulation."
"The seller is not certifying as DOT/FMVSS 132 compliant,"
However, the seller is touting the photo below in their Amazon listing for the Hikari bulbs. It's apparently for an unrelated device. It makes it appear that organizations in Oregon and Texas endorse the lights. A little shady in my opinion.
