opencore 0.8.8 Help Fix Rx480 On Monterey after installation. The screen goes black

[Nikos_260]

Hi, I have changed the SMBios to iMacPro1,1, but the screen goes black. However, during installation and at the first boot, everything was excellent and friendly, but when I rebooted, the apple logo and the loading bar was loading and then the screen went black.
 

I have installed Monterey from the beginning 3x times just because had a sound problem(Stupid idea) I had to make changes in the EFI. The 3-time install is now, we speak, has no changes and is not bootable. I also fixed the ACPI thing...

Currently, the system works with -amd_no_dgpu_accel boot arg

Please any Help?

I also tried to Change HDMI Cable to a different port, but..no luck at all
Here are my specs;

 

Asus strix RX480
Asrock A-68 FM2 DG3 Plus
16GB RAM

AMD A10 7850k

I have link for my EFI
