CachyOS Kernel for Fedora with Secure Boot

Did you just install kernel-cachyos and got hit by bad shim signature when booting? Me too. This is how I fixed it.

First, make sure you have Secure Boot with mokutil --sb-state.

Note, there's a second way of doing this by using sbctl, but I didn't want to wipe my Secure Boot keys.
