The ME minimum size should be 352256 bytes (0x56000 bytes)
The ME region can be reduced up to:
 00001000:00056fff me
Checking the FTPR RSA signature... VALID
Done! Good luck!

With no arguments or with -S, i.e. when partitions are removed, a weird issue happens — some time after boot, the NVMe drive disappears/breaks. E.g. if I boot into OS, the drive times out and detaches. If I stay in UEFI for a long time (say on a disk encryption password prompt), I/O errors appear there too.

-s seems fine.

I just noticed that the help says

  -w whitelist, --whitelist whitelist
                        Comma separated list of additional partitions to keep
                        in the final image. This can be used to specify the
                        MFS partition for example, which stores PCIe and clock
                        settings.

I guess PCIe settings could be related…

-S -w MFS seems fine so far.

Hopefully this info helps the next person who sees problems with NVMe drives specifically..
