Unable to turn off TRACKER - support unable to help :(

Hi everyone, 

We have a customer (on-site) using Ent 9.0.3, who must have their Tracker function in Sugar turned off (for compliance reasons).

Using the checkboxes in Admin > Tracker doesn't stop the tracker from running. You can test yourself, it's still fully tracking and the DB will be busy with many INSERT DB queries on a live system.

SugarCRM support has advised that we make the 'prune tracker tables' job run more frequently. But the issue is not DB storage, it's compliance.

I can see that ticking/un-ticking the checkboxes in Admin > Tracker manipulates some entries in the DB table config. I've also tried removing these rows, yet the tracker still runs.

Is anyone aware of a 'hacky' or not so hacky way of disabling this function?
