Only show page title, not excerpts, on tag pages

Hopefully I didn’t just miss an obvious option somewhere. But to elaborate, I’d like to simply show a list of page titles instead of excerpts on tag pages (ie. https://site.com/tags/foo)

The problem is that I have google maps and custom field data on each page, and when it shows excerpts that data is pulled and displayed inappropriately.

Any help would be much appreciated, thanks in advance.
