Hello Ian,
You can style most of the element properties within XamarinForms (see
Styling).
However, to change layout, you'll need to use a custom renderer and access the native Android CalendarView.
The
Android Custom Renderer and
Android CalendarView Customizations article (see "SetTextPosition" method, this would be TextPosition in C#) will help you set that up.
If you have any trouble implementing it, reply back with your custom renderer class and I'll investigate directly.
