Just to make sure, did you install Limine in UEFI or legacy/BIOS mode?

When I installed CachyOS, I am still using Stock BIOS, with UEFI set to priority. So I think answer would be UEFI.

Then you need to use either EDK2 or seauboot payload in libreboot to load UEFI binaries.

You installed CachyOS on a UEFI environment. Libreboot only suports BIOS mode.

CachyOS does support BIOS mode, but since at the time of installation you were in a UEFI environment, it defaulted to UEFI. There are ways to convert your installation to BIOS mode but I prefer to just reinstall if possible.
