How many turns on the wastegate rod can I safely do after deleting the red and green hoses?
If it's a factory rod, you won't be able to turn it in enough to totally bottom it out. To totally bottom out the actuator to keep the wastegate from opening at all (be forewarned, if you don't relieve the crimp by heating or grinding, you might twist the rod off), you need to remove the eye end and cut off about 8-10mm of threads.
Safely? No modifications are "safe" but a stock-injector vehicle can completely disable it.
How about just a turbo wastegate actuator upgrade 33psi from Amazon?
Waste of time and money. We don’t need a WG for a properly-sized and set up turbo.

Need a ‘WG actuator eliminator’. Safety wired shut is ghetto.
Some weld it shut and no actuator is required.
The truth is a cranked-down factory actuator is economically superior (free), easy and adequately effective.
The WG’s primary job is to prevent over speeding the turbine shaft and keep the wheels from being damaged. Limiting drive pressure also puts a lid on EBP to boost delta, helping to extend the life of journal bearings, etc.
If you’re spanking your stock turbo to 40psi daily, you should probably upgrade. But a stock, tuned truck that is normally driven like a responsible adult will not see enough ‘abuse’ to make a substantial difference in reliability/service life.
This is 160/30’s and RDP 4+4 compressor wheel and 360* thrust washer rebuild. Up to about 30psi of boost, EBP/Boost are close to 1:1. It starts getting ugly over 30psi - but that is rare driving conditions.
What about doing it with gold safety wire to complement the diamond grillz? Will that make it classy?

Well yes but we know that stock/mildly improved fueling won't be enough to overspeed the turbo.
