Depending on whose fake-raid it is you might be able to provide an extra driver for it, or need an extra option. I know that the intel raids have some sort of pieces that will allow dm-raid to see and manage them. Beyond that I don't know much about it as I always attempt to avoid using the fake-raid no matter what. If you find the part that makes it work that part would need to continue to be in the initramfs for any updating going forward so at best it is going to be troublesome in the future. And most of the laptops that have an M2 may also still have an open real sata location (maybe even with a cable) that you could also put a sata ssd or spinning disk in, and dual boot that way. The 2 most recent ones I have opened that came with a M2 both had a location but only one had the correct cable for power and sata.
