We lave listeners like

@rendomnet All methods of Navigation.events() return the instance of event subscription.
You can use remove method of it.

eventSubscription1 = Navigation.events().bindComponent(this);
eventSubscription2 = Navigation.events().registerComponentDidDisappearListener(({ componentId, componentName }) => {});
...
eventSubscription1.remove();
eventSubscription2.remove();

Hope this helps you!
