How to enable beard growth Geralt? (The Witcher 3: Wild Hunt)

In short, I want Geralt gradually grew a beard. The problem is that in the original game she's growing up, but I installed DLC on a new price. I decided to clean it up, but the fact that I have already passed a large part of the plot and the game does not load the save without the DLC. Can you please tell me how to enable beard growth. Maybe there is some mod...
