unity – Correcting imported animation to avoid hand going through the face of character

I’ve imported an animation from Mixamo called standing draw bow.
When I use it with my character in Unity the hand goes through the face of my character.

Is there a way to move hand a little outside the face of the character using Blender or Unity? Or am I required to make up the animation myself?

I tried modifying parameters Mixamo offers but doesn’t resolve the problem.
