Usually most banks now dispense money through a machine so getting UNC notes would be hit or miss. But there would be no harm in asking the teller either perhaps on a slow time of the day, you may find a few Tellers/cashiers accommodating to your request. Otherwise ordering notes by the brand new brick would guarantee that. Locally I've noticed certain branches issue new notes on a regular basis while other ones reissue circulated ones from their regular deposits. Good luck.
