sure, here is my EFI. This EFI won't work unless you follow "TheBlocke" method to generate your own code and paste to your own config.plist. Niko75 already provided you the link and just follow the method carefully you should be fine. BTW, thanks Niko75 for providing the link.

I have succeeded! But the method I use is not to install directly, but to install the system to the ssd hard disk by using the middle white apple machine, and then put it on the black apple machine.I don’t know if I can make a ghost mirror and share it with everyone!

But I have a problem that after waking up from sleep, the screen is black and cannot be restored to work. Please help me to see what is wrong?

Hi ennoclao

Just wondering which EFI is working with your X99 i7 5820K? I have the same cpu, same graphics card, but with a MSI X99 SLI Plus mobo.
Thanks

The motherboard I'm using is MSI X99A Godlike gaming, I think it's not much different with your SLI Plus.
I success installing Big Sur, and it works fine except sleep.
Maybe you could edit your config.plist (My system can't boot without below setting.)
Booter->Quirks->DevirtualiseMmio->True
and add MmioWhitelist to the list.
