Can the C15B Nspire take M.2 Drive

Hi everyone, I have inherited a C15B 4th gen I5 laptop with pretty decent specs from my wife, I’m thinking of updating the hard drive to SSD when I put windows 10 on it (currently running win7), but while I was looking under the inspection cover I spotted something that looks suspiciously like an M.2 port (small form factor) so my question is can this laptop run an M.2 drive? and if so what type? tried the usual google and you tube searches but there doesn’t seem to be much info about.

Can anyone shed some light on this for me?

Many thanks
