Scroll to position when RecyclerView place into NestedScrollView. Using LinearLayoutManagersmoothScrollTo and rvBlocks.scrollToPosition will not work when RecyclerView placed into NestedScrollView but this solution worked perfectly.

ScrollToPosition.txt

<androidx.core.widget.NestedScrollView
    android:id="@+id/nswContent"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rvBlocks"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clipToPadding="false"/>

    </LinearLayout>
</androidx.core.widget.NestedScrollView>

// Solution
fun navigateToBlock(position: Int) {
    val scrollY = rvBlocks.getChildAt(position).y
    nswContent.smoothScrollTo(0, scrollY.toInt())
}
