Switching from RAID to AHCI with Intel Optane
Windows 11
I tried switching from RAID to AHCI in order to dualboot archlinux following this guide, however when I reboot, instead of booting into safe mood, the machine boots into dell repair. It's only when I switch back to RAID in BIOS that I'm able to boot into safe mode, however this defeats the purpose. According to this post, you can't switch to AHCI if you have Optane installed, however without RST enabled, windows is practically unusable. My question is: Is it possible switch to AHCI while being able to use RST acceleration ?

No; if you want the RST acceleration, you must have the drive in RAID mode. There are version of Linux that will run in IRST mode, and others that can be manually installed to do so. If your chosen version won't, Ubuntu is among those that will. Since Intel is in the process of removing AHCI from new systems, it's only a matter of time before other distributions will allow IRST operation.

use RST as AHCI is an old and now obsolete standard
NVMe is the future almost, Dell as a SD card slot which is backwards compatible so that a test SDXC is legible etc but the slot has PCIe capability for modern cards
