I use Arch personally, and as mentioned you should restart every update - but you can just not update everyday (updates don’t even come at a scheduled time, it’s just packages getting new versions whenever, so by the time you finish updating there could be another updated package for you)

I think updating weekly and as necessary is a good schedule, though if you don’t update frequently and try to install something new, the version pacman will try to install will be based on your local repository information, matched to your other packages, and might no longer be available in mirrors. And you shouldn’t install an updated version of just one package, because if it pulls in the wrong updated dependencies you could break your install.
