How to retain scroll state of recyclerview inside Nesterscrollview

Question

I have a fragment which has recyclerview inside a Nestedscrollview,also instances of the same fragment is added inside a viewpager which exists in a parent fragment .when an item in the recyclerview is selected parent fragment is replaced with another fragment and on coming back to the parent fragment I want to retain the recycler view scroll position.

The viewpager and recyclerview contents are cached in the viewmodel but the recyclerview scrolls to the top, I tried different ways to save scroll state of recyclerview including saving layoutmanager scroll state in viewmodel but did not work.

Below is the layout file

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:id="@+id/root"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <RelativeLayout
            android:id="@+id/fragmentRootView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@color/colorPrimary">

            <include
                android:id="@+id/appbar"
                layout="@layout/toolbar_text" />

            <androidx.core.widget.NestedScrollView

                android:layout_below="@id/appbar">

                <LinearLayout
                    android:layout_width="match_parent"
