Trying to Find Bedroom DoorKnob

As the title says, I'm trying to find a Door knob I can put on to keep my family out of my room;

Only major issue is I'm renting and can't drill into the door, so anything with a deadbolt or basically bigger than a standard doorknob are out.
(Bought a "cheap" 80$ BTE fingerprint knob and it is always auto-locked which isn't what I want)

I'm running HA on a raspberry pi; and would like the ability to lock and unlock from within HA.

Fond of thumbprint but okay with combo code.

Thank you very much.
