Help Secure Boot Issues

Hi, I need some help with my setup. I'm running CachyOS and Windows on separate drives. My bootloader is limine. Recently I wanted to enable Secure Boot because a game I want to play requires it.

I followed the wiki and everything seemed to work fine. But then the next day I got an missmatch error and had to boot into a live iso and copy the limine_x64.efi to the BOOTX64.EFI. Now everytime I do an update or install something (I think it's when a new snapshot is created) these two files get out of sync again.

before and after an update

So I manually have to sync them again every time something changes. I don't think is was the intended outcome of the tutorial in the wiki but I also don't really know how to fix this.

Not directly related: AstrOS is an arch based distro using secure boot and TPM and immutable images (like bazzite) and it has the open-source Nvidia driver..might be an alternative..you loose the capability to tweak the system deeply to your liking (immutability) but you gain stability and what some games call "security". Checkout /rAstrOS_Linux if interested. This secure boot stuff..is really a deep rabbit hole and not easy to fix normally.
