is There any options to make Rounded Corner Border for Element Entry in common xaml (android & iOS)

Hi Everyone, I started a project which has custom textbox(entry) with border and broder radius, if i try with simply entry - android native results with textbox(entry) style with single line at bottom and iOS native results with textbox style with border blue color.
Is there any options to make Rounded Corner Border for Element Entry with just common xaml and results in same style in android and iOS.
