If you have a bootable media, CD, another distro or whatever that works,
you can grab the config from it if it recognizes M.2 SSD.  That will
give you a starting point at least.  Later on, you can remove things or
make changes as needed.  The command zcat /proc/config.gz should work
and you can tell that to put it in a regular file and if mounted, even
put it in your kernel source directory. 

Hope that helps.
