Provide Exceptions to Running GitHub Actions

I’d like to run a Github action that auto-merges PRs to a set of release branches. However, there are certain PRs that should not be auto-merged. Is there a way to provide a tag or something to a PR that the action can read and choose to auto-merge or not?

https://github.com/marketplace/actions/merge-me do you see there?

I don’t see anything there that addresses my need. Maybe I am missing something.
