I've checked the BIOS version: 7CCN62WW - latest

Try with latest changes just pushed to github.
After updating your copy of the github project, must update ACPI (make install) and config.plist.

I'm sorry, but nothing changed.
From where did you download macOS?
On what hardware did you create your USB installer?

Note: You might try disabling Nvidia in BIOS.

Also, please attach full PR files again. There is something really strange about PSXS vs. PEGP...

Image retrieved from the virtual machine (virtualbox). From the AppStore. USB created by installmedia option (again on VM).
I've attached loading video (if it helps).

As per guide, you cannot use a VM.
Note:
Note: DO NOT use a VM to create your USB. VMs are known to create invalid/corrupt USB installers. Use real hardware to create your USB installer.

It's loaded when I've disabled NVidea in BIOS. Could we fix it?

Please attach full PR files (Nvidia enabled, booting from USB) and with Nvidia disabled (booting from final EFI/Clvoer).

Try with attached config.plist + SSDT-HACK.aml in test.zip.

It has these changes for disabling Nvidia:

Note: I will need to reorganize this a bit as I'm almost certain that these changes will break models (such as my u430) without Nvidia (and probably even those with it, when Nvidia is disabled in BIOS).
