I guess you can do that also by getting the getDefaultSharedPreferences where your preferences are stored by your user settings and if you are using the FCM then here is how you can do that.

 public class MyFirebaseMessagingService extends FirebaseMessagingService {
    private static final String TAG = "MyFirebaseMsgService";
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
     //here decide by getting the value of your preference manager
     SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

     if (preferences.getBoolean("your_switch", true)){
          // Your switch is on
          displayNotification();
     } else {
          // Your switch is off
          return;
     }

  }

 }
