How can i disable list of dates in date Datepicker?

Hi guys
I like to use the following datepicker (TimeFrame). However, I like to do something extra with it which is disable some date from being selected!

for example, lets say from 01/01/2014 - 01/10/2014 is not available then disable that range from being selected!

here is the datepicker that i like to use.
