@if_it_rains    Hi. your machine and installation is done with the settings for Intels RST. If you switch to AHCI, the system doesn't find a bootable medium (SSD), and goes back to Intels RST.

Can't you install Linux with Intels RST activated?  Which is necessary, otherwise  the UEFI  doesn't initiate the PCIe  disks.   But you can take your Bootdisk out, keep only the second newly build in PCIe SSD, set the settings to AHCI , and see if the disk is detected and handled properly in UEFI.   Cheers, daddle ...
