Hi vis1946,
To enable / disable the Battle Pet tracking feature it’s controlled by the blizzard’s Track Pets mini map option. See attached image “Wow_9DTmyWGzeA.png”
Checked = Enabled
Un-checked = Disabled
You can control what you see by checking / un-checking options within Dugi Guides Tracked Pets which appears under the blizzard mini map frame options.
You would want to un-check the Collected if you don’t want the battle pet to appear if you’ve already obtained that pet. See attached image “image_2022-08-10_154414816.png”
You can also control what kind of pets to show by checking or un-checking Battle Pet Race.
