I had to know your configuration in the BIOS. It may be something wrong there. It seems strange to me that the Big Sur installer does not start on the USB.

I have same system less motherboard Asus Rampage Formula. (But they are very very similar. They wear the same patches.)

I have this settings on the BIOS, and this is the OC panic kernel (photo)... in the screen of OC I choose the 2 voice "install Big Sur"

OK, I'll check my BIOS and send you screenshots, but until Friday I can't.

We are going to test with this EFI. It has my custom SSDT, and they should be the same for your motherboard

By the way, you should get a visual interface and not that way.

Yes, I tried, but kernel panic. The same for iofamily and stacks. I have tried to patch:
Name: UNC0 _HID to XHID
Find: 554E43 30085F48 4944
Replace: 554E43 30085848 4944
But I get the same error.

hi,
thanks to xerox24 for your help and your efi folder of your system, big sur + oc 0.64 SUCCESS on R4E, I7-3930k, RX580 and all work. For boot the installation of big sur is necessary use the kernel patch ( ACPI section of OC config.plist) that work only on OpenCore 0.6.0+ and NOT on Clover for moment:

Name: UNC0 _HID to XHID
Find: 554E43 30085F48 4944
Replace: 554E43 30085848 4944

My EFI folder with Opencore 0.6.4 - 3 dec 2020 ( the .plist is in verbose mode with ACPI patch for x79 ( thanks to xerox 24 for your efi folder and help ).
