I haven't bought the BD895i SE Mini ITX motherboard yet, but I'm looking to install it in a case with a PCIe 4.0 riser, connected to a PCIe 5.0 GPU. I've heard this configuration (PCIe 5.0 on motherboard, PCIe 5.0 GPU, connected via PCIe 4.0 riser) causes issues.

I'm not sure if I want to change the riser straight away as I need to do more research on the right one to get (and it's hard when I don't have any of the parts).

So is it possible to change the generation in the bios?
