Update live activity without push notifications and with the app in background

Is there any other way to update the live activities besides using push notifications when the app is in background?

Is it possible to schedule an update, for example?

For context, I have a live activity that needs the content updated 2 hours after it's creation.

I know that the best way to do it is using a push notification, but right now I don’t have the resources to implement this.

I already tried using BackgroundTasks, but they are not very reliable, so I can't trust it.

The official documentation only mentions these 2 methods for now (remote push notifications and BackgroundTasks).
