Disabling auto-connect on Bluetooth hearing aids

Well, this is the weirdest dang problem I’ve run into lately…

Some time ago, I began wearing hearing aids. One of their features is that they’re Bluetooth-enabled; this allows connection to a mobile app, and also streaming audio. The sound quality is probably not that great compared to Bluetooth ear buds, but I use it in high-ambient-noise situations, and besides, my ears are shot anyway — hence the hearing aids. So I’ve paired them to my iMac, my iPad, and a few days ago, to my AppleTV.

The [not so much a problem as a] petty annoyance is that now, when I take them out of their charger — which effectively turns them on — my iPad and iMac connect to them automatically. So I need to manually disconnect the hearing aids from the iPad and iMac (unless I have a reason otherwise). And now that I’ve paired it with my AppleTV, it connects more-or-less randomly (indeed, it happened just now), and I need to manually disconnect.

I don’t see any way of disabling “auto connect“ on any of the three devices. I could forget the hearing aids and then re-pair them as needed, but putting them in pairing mode is less than convenient. (I need to turn them off, then turn them on — that’s the somewhat-clumsy part — and then pair them. They’re then in pairing mode for two minutes.) Disconnecting them every day is actually simpler.

Any thoughts? Can “auto-connect” be disabled? Is there some shortcut that can connect or disconnect a specific Bluetooth device? (“Hey Siri, disconnect hearing aids”.)

TIA,
