All of your servers will be listed in Adaptive Application Control group recommendations. You can accept as-is or modify these groups. After you activate the group you will get app audit alerts. To remove the server just remove it from any active AAC groups.
I don't think there is a way to turn off the groups recommendations in the AAC page.
If you are seeing a recommendation to turn on AAC for a server you can set a recommendation exclusion if needed.
This is of course an audit-only solution. Though it leverages AppLocker. You cannot use both, it takes over the AL policy,
