Can we make akshara run 'grub-mkconfig' only if grub is installed?

I have a deep deep seething hatred for grub that started back in the opensolaris days. I run systemd-boot or refind on all my machines. Can we make the exec call to grub-mkconfig in akshara be configurable based on the presence of grub packages in the expanded system.yaml or perhaps run as a hook? I am a python developer and would be happy to code this up and send over an MR.
