its possible to create a transparent entry in xamarin.forms iOS like Android?

i want in iOS the entry looks like a entry Android, the entry android don`t have border, but the entry iOS have a border.

var entryStyle = new Style (typeof(Entry)) { Setters = { new Setter { Property = Entry.TextColorProperty, Value = Color.Black }, new Setter { Property = Entry.PlaceholderProperty, Value = true }, new Setter { Property = Entry.BackgroundColorProperty, Value = Color.Transparent }, } };

Thank you very much for your help
