...No idea: I'd have to open my computer !

And I'd better leave that to a professional: before you asked and I looked it up on Google, I didn't even know what an M2 slot was 😊!)

Thanks for alerting me to this point though!
If you can post the full specs of the Dell model, I can have a look as the M2 drives just plug in easily, if you have a DVD rom slot you can use that for a SATA SSD bay to give an extra internal hard drive.

It is very kind of you, musocity, to offer me this help.

Unfortunately, apart from the model name (Dell XPS 18), I do not have the detailed specifications of my device.

Also, there is no DVD slot: the Dell XPS 18 is shaped like a maxi pad (18-inch screen) with a separate keyboard and is therefore very thin.

This is a model that Dell manufactured ten years ago, but which has been discontinued for several years (which is a shame because it was a very original product and ideal for a pianist ☹) :
