You can create a global action in the main navigation graph Like:

<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main_graph"
    app:startDestination="@id/x">

    <fragment
        android:id="@+id/x"
        android:name="x"/>

    <include app:graph="@navigation/x" />

    <fragment
        android:id="@+id/firstFragment"
        android:name="x"/>

    <action
        android:id="@+id/action_global_to_firstFragment"
        app:destination="@id/firstFragment" />

</navigation>

And then call it with the id:

navController.navigate(R.id.action_global_to_firstFragment)

The navController must be the defined in the ActivityContainer, if it generate a destination error, maybe you aren't using the main navController
