ASUS Strix X570-I PCIe Bifurcation Support

Hello!

I hope someone on here can help me out: I’m looking to bifurcate the x16-slot on my X570-I board, as I’m trying to run both an AMD as well as a NVIDIA graphics card. However, ASUS doesn’t really support this kind of bifurcation, only when in used in conjunction with their NVMe RAID PCIe extension card. I figured since bifurcation is officially supported on Ryzen, and the Gigabyte one does even fully support it, that it may be possible to mod the ASUS one. I already looked around with AMIBCP and Flashtool, but couldn’t find anything.

Any help or direction pointer is welcomed!

Thanks!
