[Solved] Internal mass storage not appearing

Hello forum,

I got a new baby to deal with.
I would like to backup the original OS and put my system over that space. Unfortunately the kernel fail to assign the PCIE mass storage (aka SSD).

$ lspci |grep -i pcie
#  nothing
$ lspci |grep -i nvme
#  nothing
$ sudo journalctl |grep -i pcie

$ ls /dev/n*
/dev/null  /dev/nvram

/dev/net:
tun

How do I mount that mass storage?

EDIT
SOLUTION
Following the information provided I could dig to the BIOS and I found the option to disable Intel RST and using the AHCI instead.

do it good first, it will be faster than do it twice the saint

If not please post the full dmesg output along with the lspci -nnk entry for the device.

Re: [Solved] Internal mass storage not appearing

Thank you for the reply,
The hardware is different, because the BIOS reports a Samsung brand. I'll be back here once I had tried the linux-lts.
EDIT
I tried the kernel LTS, but no improvements. I created a report in the hope to give the necessary to study the case.

lug 20 17:51:24 AcerXC886 kernel: ahci 0000:00:17.0: Found 1 remapped NVMe devices.

It looks as if you have that foolish RAID (FakeRAID / Intel RST / Intel Rapid Storage Technology(R)) enabled instead of AHCI in your BIOS. That could be is unsupported.

Lines before or after your log keyword match might be relevant as well, so you should not only look at filtered logs.

Re: [Solved] Internal mass storage not appearing

I saw some new BIOS version for this machine, but my machine is just three days old that I'm afraid to write the newer BIOS. Besides that I don't know whether will produce any benefit for this case.
EDIT
Thank you all for the given information, so I could find the solution. The solution is laying around the BIOS option, as you may see in this picture.
