Can we prevent Windows from marking NVMe drives as removable?

I've noticed recently that when adding NVMe drives to Windows, it has a tendency to mark them as removable. I think this is more likely on "enterprise" NVMe SSDs, at least in my experience. For my own PC or less critical stuff, I'm not too bothered…
