if baloo is run as a service (and it probably is) then you can use
“sudo systemctl disable baloo”
to disable it. I am guessing on the name of the service since I don’t use baloo, but you may be able to find it with
“sudo systemctl list-units”
and parse that for the actual service name.
Since you have balooctl you might be able to control it more directly with its own commands that often can be found with something like “balooctl --help”
Usually disabling does not also stop at the same time. Disabling infers that it will not automatically restart. Stopping involves stopping the currently running instance. Maybe “balooctl stop” would work.
