Hey Jason,
Regretfully, it’s not possible without custom development and that is outside the scope of our product support.
If you are a coder, what you can do is override the Post Meta function of the stack. Go to framework\functions\frontend and open the PHP file of the stack. For example, if you’re using Integrity, open integrity.php.
In that file, you find the Integrity stack’s post meta function and that is x_integrity_entry_meta
. Copy the whole function to your child theme’s functions.php and override the code block that displays the categories. You need to turn it to display tags instead.

What I mentioned wouldn’t make sense if you’re not a developer so if that is the case, you need to consult with a 3rd party developer.
Hope that helps and thank you for understanding.
