Update: apns-collapse-id is already available for FCM v1:

FCM provides a specific set of delivery options for messages sent to Android devices, and allows for similar options on iOS and web. For example, "collapsible" message behavior is supported on Android via FCM's collapse_key, on iOS via apns-collapse-id, and on JavaScript/Web via Topic. For details, see descriptions in this section and related reference documentation

In order to bundle notifications in iOS, you'll have to specify a thread-id:

Provide this key with a string value that represents the app-specific identifier for grouping notifications. The system groups notifications with the same thread identifier together in Notification Center and other system interfaces. For local notifications, this key corresponds to the threadIdentifier property of the UNNotificationContent object.

However, there is currently no parameter counterpart for thread-id in FCM. What you could try and do is make use of a data message payload and specify the thread-id as a custom key-value pair.
