To be able to boot from Windows installed on NVMe drive, several things must be true:
1) PC must be in UEFI mode
2) Drive must be formatted using GPT, not MBR
3) PC must support native booting from NVMe drive
I suspect the latter is not true with your PC because if it was, there would be an m.s NVMe slot in your motherboard -- and I don't see one in the picture. Windows 10 has native NVMe drivers, so you can use the drive, but you can't boot from it.
