By default, dpkg will silently upgrade unmodified conffiles to the
current version, without prompting the user at all.  If you've modified
the conffile, dpkg will prompt you to find out if you want to keep your
modified version, upgrade to the new upstream version, see a diff, or
run a shell; dpkg will default to keeping your modified version.

So, unless you've changed a configuration file, you already won't get a
prompt on configuration upgrades.  If the configuration upgrade might
matter to sysadmins, the Debian package should provide an upgrade note
in NEWS.Debian, or upstream should provide a note in NEWS (which I wish
apt-listchanges could show, at least when it follows a standard format).
