Heroku review apps and github integration

Question

We have a heroku review app pipeline configured with github integration.

Currently, every time after a new app is created, we have to go in and manually disable automatic deploys in the UI here:

I was looking around for one of the following options to remove this manual step:

• call an api to disable auto-deploy on a review app
• change a pipeline level setting that determines the default value of auto-deploy for new review apps that get created

but so far I haven't been able to find anything.

Any suggestions for how this might be achieved would be much appreciated.
