custom field render date field: Turn Off Calendar- Mobile

The calendar pop up for date fields does not work well with my mobile layout. It gets stuck some times partially viewable and won’t scroll. Plus I am using it for date of birth so it doesn’t work great in that it defaults to current year. Is there a custom field render to turn off the calendar pop up?

Since the standard calendar renderer uses jquery ui’s datepicker widget - customizing it is pretty straight forward.
