Disabling the current tab in a bottom navigation controller

I'm using Jetpack Navigation to handle the bottom navigation controller. It works great; however, I am looking for a way to improve the UX.

Is it possible to disable the tab that the user is currently navigated to?

I'm able to "spam" the current tab in the bottom navigation, which reloads data & the UI unnecessarily. If this behavior (of re-tapping the current tab) is intended, is there a way to retain the state of the fragment, so that when navigated away & to, it doesn't recreate?

How I handle the bottom navigation:

navController = NavHostFragment.findNavController(navigation_host_fragment)
NavigationUI.setupWithNavController(bottom_navigation_view, navController)

As per this issue:

Feel free to set a OnNavigationItemReselectedListener, which takes precedence over the OnNavigationItemSelectedListener set by NavigationUI: setOnNavigationItemReselectedListener

bottom_navigation_view.setOnNavigationItemReselectedListener {
  // Do nothing
}
