[NV] Is there any way to remove the forwards/backwards leaning in third person?

[maletir]

In third person, my character leans forward or backward depending on where I aim, whenever I have a weapon readied.

 

This usually leads to a very strange posture, even when looking straight ahead, and I was wondering if there is any way to remove the leaning and have the character keep a straight back no matter where I aim?
