Dynamic Config based on changed files

Build Environment
1

I have a CI/CD pipeline that looks similar to the one below. Where on changes that are pushed to main (or manually triggered by API) I want to build and deploy the code. However, I’m now trying to implement such that if changes are only in the helm/ dir. I’d like to do a deployment without the build part. My structure and relevant config files are shown below.

I’ve successfully managed to make it work so that if there’s changes to any file (except in helm/*) it triggers build-deploy and if there’s changes only in helm/* it triggers deploy. But; in the case where changes are made to both the helm/* dir and somewhere else I only want build-deploy to run.

Any idea of how this could be solved?
