Actually you don’t really need the update popup. If you disable it, you’ll still get the update error message if avast! for whatever reason stops updating (or fails to do so). The reason why i say it’s not really relevant to see the update popup is in the fact that even though regular VPS updates are released twice a day, Streaming Updates are received every 5 minutes. And for these, you don’t see any popups at all (either way).

But sure, they could add an option for that if they have added so many of them for various other things…
