Here is the tutorial for injecting SLI certificates into ITX motherboards with PCIe Bifurcation capabilities.
There's no need for silly driver workarounds, works with Nvidia drivers out of the box.
PDF: LINK
UPDATE: I can confirm that the process is exactly the same for z390 boards and someone also validated that x470/x570 also work
UPDATE2: Asrock Z390 Phantom Gaming-ITX/ac includes an SLI certificate by default (no need to inject for this board)
I'm leaving the below for reference but its just personal notes. Not required for Intel anymore.
For Intel the process is slightly different because the UEFI / BIOS is in a different format. I'm trying to find the tutorial file I wrote up, however if I don't, here are the high level steps for Intel boards:
dump aml from z270 donor board using clover (f4)
convert aml to dsl using:
iasl.exe -oa dsdt.aml
Open dsdt.dsl using MaciASL
Copy SLI license key to clipboard
dump aml from z270 recipient board using clover (f4)
convert aml to dsl using:
iasl.exe -oa dsdt.aml
Open dsdt.dsl using MaciASL
Paste in SLI license key
Exit
use iasl to convert dsl to aml using:
iasl.exe -oa -f dsdt.dsl
