I think you should disconnect the Drive 0 and see if the nvme boots.
Want another opinion @phillpower2 @Pyro.
Phillpower2 & Pyro. to save reading everthing.
If you look at the pic in post#12 it shows efi on disk 3 NVME.

In my opinion he does not need disk 0 for booting.
UEFI does not use the System Reserve Partition.
