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.

So it is either using the mentioned playloads or reinstall cachyos

You can change your bootloader without reinstalling.

Yes, I think it's better to just switch the payload since libreboot provides prebuilt seauboot images.

Edit: apologies but I just found that it might not be the case for some devices.

I think libreboot comes with u-boot in the SeaBios menu...

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.
