under pressure
Guvment says the warning light should come on with a 25% drop in pressure, or also in the case of overheating.
I have been able to reduce my tire pressure by about 10 psi and no warning lights came on.
Having said that, I DID buy a TPMS fob on Amazon. $33 to my door.
Worked great! Had it reset in under a minute. Not a newer diesel, but this may help someone else reading this thread.

This is why I only run nitrogen in all my vehicles now. My truck used to drive me nuts going from our beautiful -40C winter weather and then parking in my heated garage overnight was enough to trip the sensors every time. I changed out to nitrogen and they never bothered me again.

Don't quote me on this but I'm pretty sure you can re-learn the sensors to whatever pressure you want and then they'll monitor it for that. You just need to use the little remote the truck came with. I had to do it once and it was a PIA but luckily you should only have to do it 1 time. Just drop all 4 tires to your desired pressure of 65 and do the re-learn and you should be good to go.
Also, the 2011+ trucks don't even include that remote anymore.

It is my understanding that the threshold for the TPMS sensors is set at 75% of the recommended 65psi front and 80psi rear pressures. I like to run my rears lower than my fronts when unloaded so I retrained the system and told it that the fronts were in the rear and the rears in the front. I aired down to 80% of recommended and after a few days the light came on so I went to 85% which puts me at 68psi for the front tires and 55psi for the rears and have not had the light come.
Per Michelin and my actual axle weights I can go even lower without safety issues.
