In order to stop ControlPoint Services from Discovering information in your SharePoint Farm, you will need to stop the following services:
- Metalogix ControlPoint Discovery Timer Job in Central Administration
- Metalogix ControlPoint Scheduled Job Review Job in Central Administration
- On the Web Front End Server where ControlPoint is installed, on services.msc, you can find the Metalogix ControlPoint Discovery Service as well.
These are all the jobs that usually run on a schedule to make ControlPoint usable, disabling this will stop crawling data for ControlPoint reporting.
