This turns off the automatic checking and downloading of updates by Gnome Software and any other PackageKit based system. But there is also a cron job for dnf that updates the metadata regularly (daily?). If that's a concern for you, you can disable that one as well.
But as I discovered, if you disable that, and simply run
dnf update
it will never think there are any updates available.
To update entirely manually, I need to run:
dnf makecache dnf update
these days.
