That could be handled with a communal spaces, a HOA tends to end run by the “Karens” trying to micromanage everyone, and the boys who think they’re Wyatt Earp running around enforcing stuff.

There’s no excuse for meddling in the affairs of your neighbor, unless what they are doing is literally dangerous, as much as a flamingo in the yard pains me to see it doesn’t actually hurt me.

Same to say my raised beds don’t hurt anyone, breaking the boring theme of crappy lawns isn’t reason to tack notices to the door, and a lot of them will attack people near the HOA not just the ones in it.
