XPS 13 9305 - Cannot set AHCI in UEFI

 Hey folks,

I am trying to set up a system for dual boot.  One of the steps is to set AHCI (from RAID) in the UEFI.  When I toggle the button to AHCI (from RAID), then hit "Apply Updates", it goes back to RAID.  Even after trying to save and exit, when I go back to the UEFI (reboot and F2), it is still set to RAID.  I have tried this multiple times, it always reverts back to RAID.  Is there some other setting I need to update first?

Linux shows that there are no AHCI devices available "dmesg | grep -i ahci". It does show RAID devices "dmesg | grep -i raid".

 

The developer version of the XPS 13 allows the AHCI setting to be set in the UEFI.

Why did Dell disable that in this version of the laptop?

Is there a way to re-enable it?

Why would Dell intentionally cripple the UEFI?

Following up on this.  I upgraded the ssd to a bigger drive.  I was then able to switch the setting.  It looks like the included drive could only support RAID mode.  The new drive, oddly enough, only supports AHCI mode.
