Set the same elevation for all cards in recyclerview kotlin

Question

I'm using this card xml in my item for recyclerview and it looks like the shadow increases when the position comes more down, but I want to make it one for all of them

<com.google.android.material.card.MaterialCardView
        style="?attr/materialCardViewElevatedStyle"
        android:id="@+id/crd"
        android:layout_height="wrap_content"
        android:layout_width="0dp"
        app:cardCornerRadius="8dp"
        app:cardElevation="2dp"
        app:strokeWidth="0dp"
        android:layout_margin="4dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent">

enter image description here

I searched for a solution but I didn't find
