Yes, in the config, under the category section, you can set TrackedByDefault to false for each category. That will make it so NEW players won't have those categories tracked.
Note, that only changes it for new players. Existing players will still have those tracked, and they will have to go into the skill menu and click the blue category buttons for each category to untrack them.
If you don't want anyone to be able to track anything, under the Tracking part of the config you can set MaxTrackedItems to 0, this will make it so there won't be anything tracked there ever.
Check out the tracking section in the documentation if you need more info.
