MB is msi z590i unify.
bios download: https://cn.msi.com/Motherboard/MEG-Z590I…pport#down-bios
I don’t want to modify this bios, I just want to ensure "is all msi itx board can’t support pcie pcie bifurcation“

Bacause AMIBCP can not show the setup configuration so i can not ensure(Z490I UNIFY must not support)？I have bought a c-payne PCIe Bifurcation Card. The PCIe Packet Switch (PLX) Cards is very expensive and not support pcie4.0(pcie4.0 PLX chip is very expensive).
