As this is an AMD machine - and as it's a workstation, not server, perhaps this is why they've restricted it in BIOS.
I'm not too much of an expert in PCI express - but if this workstation has 4 PCIe root complexes/host bridges, each capable of x32 PCIe 4.0 lanes - and there are no multi-root PCIe switches, wouldn't a lane physically have to communicate with just one PCIe root complex/CPU "port"?
