According to ASRock support, support for bifurcation was added via BIOS update to other ASRock boards as well,
I asked about B550M Steel Legend and B550M Pro4 and was answered that:
"Both of B550M Steel Legend and B550M Pro4 board support "PCIe/GFX Lanes Configuration" feature."

The slot that supports bifurication would need to be a x16 slot that can do 4x4x4x4 (four m.2 ssd's). A PCI x8 slot can only do 4x4 ( two m.2 ssd's). Of course the board would have to be set for that configuration as well, if it supports it. Nvme ssd's for m.2 slots only support x4 lanes from what I understand
