Someone else will correct me if I'm wrong, but AFAIK GRUB does not have 
native support for NVME devices and relies on the system firmware to 
access them. So if the system firmware has no support for NVME either, 
I'm afraid you're out of luck.

If the motherboard has an M.2 slot, it is unlikely that the firmware 
does not have support for NVME. Note however that some UEFI firmwares 
may support NVME only with EFI boot, not with BIOS/legacy boot.
