Different navhost fragment for every activity

Im building an app with conditional navigation based on the values of the login token received. So I have three different landing pages for my app based on three diffrent values i revceive after decoding the token. So Iam using three different activties each with its own set of Navigation Graphs and NavHostFragment. Problem is as soon as I declare another navhost fragment in second activity, app is crashing whenever that activity is opened, with error: "Binary XML file line #36: Duplicate id 0x7f09018a, tag null, or parent id 0xffffffff with another fragment for androidx.navigation.fragment.NavHostFragment"

Following is how I declare navhost fragment in first activity:

<fragment
    android:id="@+id/nav_host_fragment"
    android:name="androidx.navigation.fragment.NavHostFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@+id/bottomNav"
    android:layout_below="@+id/appbar"
    app:defaultNavHost="true"
    app:navGraph="@navigation/navigation_graph" />

And this is how I declare navhost fragment in second activity:

<fragment
    android:id="@+id/nav_host_fragment_supervisor"
    android:name="androidx.navigation.fragment.NavHostFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@+id/bottomNav"
    android:layout_below="@+id/appbar"
    app:defaultNavHost="true"
    app:navGraph="@navigation/navigation_graph_supervisor" />

Please help.
