Hi Ricardo,
This issue is found with my developping device which use aditional BAR, the RST driver is working well, I think the issue is UEFI driver which support NVME raid, but the UEFI driver seems has issue with allocate and use BAR, so please confirm with intel chip set UEFI driver team to confirm does the UEFI driver scan all BAR of NVME device.

Regards,
Andy
