XPS 15 9560 switch os drive from 2.5’ SSD to MV2

Hello,
I have an XPS 15 9560 with a 2.5 inch SSD. I would like to replace the 56W battery with a 97w battery but the SSD takes the place of the battery.
Is it possible to clone the SSD to an M2 drive and remove the ssd to install the big battery?
If so, can you tell me:
useful references to buy a compatible M2 disc
a method to clone SSD to M2
how to change boot disk in bios

If you have these answers, you will have my eternal gratitude...

Thanks

Phil
