All Domains software is installed by the domain owner using the Installatron tool. As such, it can be quickly managed and uninstalled via the My apps interface in cPanel.
First, log in to your domain and go to the Dashboard. You should see the Applications section near the top (if not, scroll down). Click or tap My Apps from that section to list your existing installations.
WARNING: Uninstalling an app will permanently delete all files and data associated with the app. This process is not reversible or recoverable. Before proceeding, make sure you have backed up anything you want to keep a copy of, and that you have selected the correct app to uninstall.
This list shows all the software that you have loaded using Installatron. To uninstall an app, click the X next to its listing. You will be asked to confirm the uninstall. When you're ready to proceed click Uninstall in the lower-right hand corner.
Installatron will display a progress bar while uninstalling your app. When it's finished you can click Tools in the upper left to go back to the Dashboard.
