Is there a way to specify the PR branch for YAML pipeline in Azure DevOps

Question

Is there a way to just specify that a pipeline runs on the PR branch? I am fairly new to Azure Devops Pipeline YAML.

Currently the trigger is:

trigger:
- master

Answer 1

It seems it can be done via:

trigger:
  branches:
    include:
    - features/*
