Disable the Shadow Animation in Shell TabBar

If I switch between my different tabs, I allways get this little click animation that looks like a shadow or sth. I use a custom Renderer for my Shell, but how can I disable this animation?

Here is a picture of the click animation

I found the solution by myself. Here is my code:

        public void ResetAppearance(BottomNavigationView bottomView)
        {
            
        }
        public void SetAppearance(BottomNavigationView bottomView, IShellAppearanceElement appearance)
        {
            Android.Graphics.Color elevationBGColor = ((Color)Xamarin.Forms.Application.Current.Resources["ElevationBGColor"]).ToAndroid();


            bottomView.LabelVisibilityMode = LabelVisibilityMode.LabelVisibilityUnlabeled;
            bottomView.SetBackgroundColor(elevationBGColor);
            int[][] Tintstates = new int[][]
            {
                new int[] {-Android.Resource.Attribute.StateChecked}, // unchecked
                new int[] { Android.Resource.Attribute.StateChecked}  // pressed
            };

            int[] Tintcolors = new int[]
            {
                Xamarin.Forms.Color.White.ToAndroid(),
                ((Color)Xamarin.Forms.Application.Current.Resources["PrimaryColor"]).ToAndroid()
            };

            ColorStateList TintList = new ColorStateList(Tintstates, Tintcolors)

            bottomView.ItemIconTintList = TintList;
            bottomView.ItemRippleColor = null;
        }

In this code I also set a color change to the item i selected in my navbar, but the code i was searching for was

bottomView.ItemRippleColor = null;
