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
