Fix DRM for Netflix (Safari) and Apple TV

[madvinegar]

Hello to all.
The details of my system can be found in my signature below.
I am on Big Sur 11.5.1 with SmBios iMacPro1.1 (and opencore 0.71)

I cannot get the DRM to function properly. Netflix can only be used in Chrome. When I use Safari I get a red screen (but I can hear the sound).
In appleTV I get a green screen.

I have tried shikigva=128, (or 80) but has not worked. I tried these as boot arguments but also in device properties. No fix unfortunately.

Is there any method to make this work?
I attach copy of my config.plist (I have deleted the platform info entries).

Many Thanks

Apologies, I just seen the below tutorial and this fixed my issue. More specifically I added unfairgva=1 as boot argument.
