I did a similar thing, installed Samsung 2 TB SSD NVMe 960 Pro on my Dell XPS 13 9360. It works without a problem or any additional installation steps with Ubuntu 17.10, but the thing I noticed is that there is now noise(coil noise, coil whine) in my headphones every time there is load on SSD, and even without heavy load there is lower small noise. I am not sure if it is SSD, but Googling around it seems this is the issue with some high density Samsung SSDs, and it seems XPS is even more susceptible to this than other devices.
