Disable FCM, default to GCM/APN

Please provide the following:

  1. SDK Version: 35
  2. Platforms(Android/iOS/web/all): Android / iOS

Is there a way to disable FCM, I use Firebase so that I can send instant chat messages with cloud firestore, I also use deep linking so require the googleServicesFile property to be present in the app.json file. But now any push notifications seem to default to using FCM.

If I cant turn off FCM, is there a way to tell my app to use APN, or GCM by default
