What I've been doing is commenting out the EFI partition line in fstab of all 
distros except the
one I wish to retain boot priority in NVRAM. So far it seems to be effective in 
preventing
updates usurpation. Can anyone think of reason(s) why this might be a bad idea? 
So far, I've
come up with nothing.
