Nextcloud Office does not delete.

I have 02 instances on AWS with Ubuntu 22.04.3 LTS, one with Nextcloud and the other with Onlyoffice. I would like Onlyoffice to be my main collaboration platform. I deactivate Nextcloud Office, delete it, and when the instance turns off and on again, Nextcloud Office returns to the Activated Applications list and remains as the main collaboration platform. How can I stop him from coming back? I would like that, when I restart or reconnect my Nextcloud instance, Onlyoffice remains as the main collaboration platform.
