Dual Hack-Win11 [4090+6900xt] - i9-14900 KF

I installed a 4090 and 6900xt on the same machine, the AMD just for MacOS.

Then I compiled SSDT-GPU-DISABLE.dsl --> SSDT-GPU-DISABLE.aml to disable NV in Opencore.

But I am not sure is it is actually disabled.. how can we make sure of it?

By the way, I am not able to boot the machine with secure boot enabled.
It's on Opencore 0.96, all EFI's are signed, it just reboots when I enable Secure Boot on Bios (keys included there)

Also, I cannot see any core over 5Ghz.. might it be cause of the chosen SMBios?

I am on MacPro7,1, when I choose iMAC1,1 ... I loose the keyboard .. :(

​

Any idea how to troubleshoot it ?
