Jenkins+Stash+Git (need to trigger from Stash, not from Git commits)

[kartik bhatt]

I have configured Jenkins, Stash, and Git.  Builds are triggered when I push changes to Git, when a new pull request is created, and when I trigger a build manually from Stash.  I would like to trigger builds only from stash ( manually by pressing the "Trigger build" button).  Is there a way to configure my Jenkins project to NOT trigger on Git commits?
