Subsonic .45 from a suppressed plinking pistol or maybe get some subsonic .300 blackout from a suppressor.
Ask a close friend to buy it for you with cash and then do a transfer. Every full moon skulk out to the nearest intersection and pop the bitch from there, they'll learn it doesn't belong there. If you live in a suburb know probably at least half your neighbors have street facing cameras now.
Air rifle would also do the trick. And I'd suggest 80% lower instead of a transfer.
