How can I exclude changes to the pipeline yaml file to trigger a build i azure devops?

Question

Working with Azure devops, and piplines yaml files. There is a trigger on the develop branch. However, when I am saving changes to the yaml file, it triggers a new build.

This happens cause the change to the yaml file is a new commit, captured by the trigger.

So my question is, how can I exclude changes to the yaml file, from triggering a new build?

With changes announced here Support for wild cards in path filters we can now use wild cards:

Wild cards can be used when specifying inclusion and exclusion branches for CI or PR triggers in a pipeline YAML file. However, they cannot be used when specifying path filters. For instance, you cannot include all paths that match src/app//myapp*. This has been pointed out as an inconvenience by several customers. This update fills this gap. Now, you can use wild card characters (, *, or ?) when specifying path filters.

So you can now:

# specific path build
trigger:
  branches:
    include:
    - master
    - releases/*
  paths:
    include:
    - '*'
    exclude:
    - '**/*.yml'
    - '**/*.yaml'
