Bit of a situation around mosquitto add-on, Hass OS v10

Slightly complicated situation.

Basically Hass OS v10 (which my home assistant instance has installed without me asking it to twice now) isn’t compatible with mosquitto add-on version 2.

It shows an “out of memory” error.

If I downgrade to version 9.5 everything works perfectly.

I CAN happily upgrade to a later version of Mosquitto add-on, but I don’t want ANY security - and later versions of mosquitto seem to insist I use various options which I neither need nor want.

Any tips?

Ideally Home Assistant wouldn’t install this ‘upgrade’ without me expressly telling it to, and also ideally that self same upgrade wouldn’t break my mosquitto add-on.

Thanks
