AHCI mode is actually activated in the UEFI, and I also tried changing some numbers via regedit, but that didn't seem to help.I read online that magician has a bug and sometimes doesn't read AHCI correctly, and also that you can detect if it works correctly via device manager but that kinda puzzled me.

Any other methods to forcefully activate AHCI?

Windows version is 21H1 OS Build 19043.1052

Thanks in advance!
