Ok. Given that this is a "can't see nvme"-style problem, I've found:

("Linux Mint installer cannot find nvme drive on Dell XPS 15 laptop")

so one thing is certain: you are not alone! There appear to be 2 lines
of approach: either changing bios settings for the storage controller,
or changing kernel boot parameters (such as
"nvme_core.default_ps_max_latency_us=0"). Although I consider changing
bios settings to be safe (it *should* not damage your existing data),
if you are unhappy doing so, there is always another "safer" option:
remove the drive and access it using an external nvme-usb adapter.
It's your call.

HTH, J :-)
