M2 Pcie slot not detecting GPU

Hi there,
I was trying to get another card up and running using the M.2 PCI slot and riser. this does not seem to pick up in hiveos. even when I remote connect into the miner application, it does not detect my gpu.

Brand new GPU and it works on the normal riser.
I cannot see any BIOS option to enable etc. Does anyone have any ideas around how I can trouble shoot? I have another riser and M2 adaptor, however these all came in the same batch and I have not other Mother board that can run it to test if it is and issue or not.

Should Hiveos pick it up? is there some command I can run in linux to detect new cards or devices or find any failed loading items on boot?
Thanks in advance
