Hello, I'm the happy owner of a XPS 15 9510. I'm facing an issue in the BIOS : I can set the storage option to AHCI/NVME and save. But when I quit and restart, this option is reverted back to "RAID on". It seems that it appeared with the v1.7.0 BIOS upgrade. Those options seems to have the same issue : Block Sleep and M.2 Port switch.   I tried to : - downgrade my BIOS (but was unable to downgrade); - reflash the BIOS v1.7.0 (from the BIOS3, from the internal NVME and from an external USB); - reload the Factory default options.   Any ideas on how-to solve that ? Thx
