Avast settings question

I recently installed and am setting up the Avast Endpoint Protection Suite. In the Enterprise Admin console under the computer catalog settings, under service, what does the setting “overwrite avast settings every…” do? If this is set to 30 minutes, does this just mean that it will check every 30 minutes for changes to the computer settings and push them down if needed, or does it mean something else? Settings that I set, I don’t want them to be over-ridden. Just trying to understand what this option does.

Also is there any way in the console to set the pop up duration settings and the show monthly security report setting? I can set everything else in the console but I don’t see a spot to set these settings. Or can these only be set individually on the computers?

Thanks,
Andrew
