This Is one of my later OC EFIs. I don't have my machine handy to give you my latest. This one should boot Big Sur. I am using a Patched EDID in this config. It limits the screen to 48hz instead of 60hz. Latest Whatevergreen has seemed to have fixed this issue though.

Thanks for your help.
I did a little modification and it work well.
The only problem is now combo jack.

I don't think I ever got the combo jack working, but it's not a deal breaker for me.

Figured I would add my latest EFI. This is running Opencore 0.6.6 on Big Sur 11.1, 4K Display at 60Hz. This EFI is running the Modern UI Opencore icon pack. Currently I use the MacBookPro 13,3 SMBIOS. I don't use HDMI output so I cannot say if it works or not. Besides that everything else is working.
