Preventing changes of GRUB_ENABLE_BLSCFG value

In /etc/default/grub I have GRUB_ENABLE_BLSCFG=false
A “dnf update” that included grub2-tools changed it back to GRUB_ENABLE_BLSCFG=true
Is there some way to prevent this from happening in future grub2-tools updates?

I note that the update didn’t change other entries back to their default values. For example, it kept my GRUB_TIMEOUT=20
