Question
My SYS-421GE-TNRT has three NVME drives (2 x Micron M.2 7450 and 1 x Micron 7500 U.3 drive), I can see the NVME drives in OS but BIOS doesn't show the drives.  Is this normal?

Answer
Answer: X13DEG-OA (BIOS 2.6) has NVME firmware source sets to Vendor Defined Firmware.  With Vendor defined firmware, the EFI BIOS will read the Micron NVME EFI driver aka VPD OptROM.  If you don't see the Micron NVME drives in "Advanced BIOS" page, you can check UEFI shell for the BLK devices, those NVME drives should be display in UEFI shell as Block devices.
