Back to the original question:
I've not had a Dell with this option yet, but I understand Dell uses RAID with
NVMe drives because it allows Intel RST drivers to work with most/all NVMe
drives. I'm not sure if any of the Dell onboard software to restore the Win10
OS also depend on this. Once you initialize the OS I think you won't be able
to run it in a different mode. http://forum.notebookreview.com/threads/why-does-dell-set-the-bios-to-raid-always.832016/
However, I've seen it mentioned in various places Linux will not be able to
see the drive if RAID is selected - I don't know if this is still the case. https://www.dell.com/community/XPS/Pros-Cons-AHCI-vs-Raid-On-XPS13-9300-NVMe/
