Yes definitely. I went on another ride today and right now, I have been able to regulate the amount of noise from the rear brake. I do this simply by not holding down the rear brake so hard and so quickly. I put most of the pressure on the front brake while using the rear brake to assist with the stop. However, if I hear the squealing then I loosen up on the rear brake or if I need to stop quickly, then I press down on it even harder.

Strangely enough, the squealing occurs when I put a medium amount of pressure on the rear brake. A little pressure or a strong hard amount minimizes the squeal.
