I apologize; it seems I was not sufficiently clear.

By "downgrade the UEFI" I meant "revert the installed UEFI to an older
version" - what you were attempting to do by "reflash"ing the "BIOS".

I was looking for a response like "double-clicked the EXE which I got
from [place] and followed the prompts, selecting [option] when given a
choice" or "ran the EXE which I got from [place] from the command line,
using [list of command-line parameters]".

If you did it via a graphical interface, and ran into a no-downgrade
wall, it may well be worth looking at the documentation which is
probably available along with the download; it may provide a
command-line version of the process, which might support parameters to
tell the tool to allow the downgrade to occur.

(Downgrading is suboptimal, but would be one way to address the
proximate issue.)

My first suspicion would be that the installer environment does not
include - or, at least, is not loading - the necessary drivers for some
portion of the stack which is in use when the "RAID" option is enabled.

I don't think we've reached the stage of concluding that there is no
such Linux driver, at least not yet.

What steps have you taken to try to identify the device for which a
driver is needed?

A 'lspci' verbose report, from one of the live environments where the
NVMe device does not appear, might be helpful as a starting point in
doing that. I'd probably start with 'lspcn -nnn', and look in the output
for either anything which mentions "NVM" or "nvm", or any unidentified
devices.

You're quite welcome.
