Apple TV 3 Auto-Discovered

Whenever I reboot Home Assistant it auto-discovers one or more Apple TV 3’s, which actually are Neat devices that are AirPlay capable and that I don’t want to integrate into Home Assistant. I wind up dismissing the notifications and ignoring the auto-discovered devices every time, but that only lasts until the next reboot. Is there a way to suppress discovery of these devices permanently? Thanks in advance and apologies if this has been asked and answered. I’ve scoured the forum and haven’t found this issue.
