Am I allowded to modify the polygons of Mixamo's characters and use my graduation work?

Hello! As checking license, I am allowded to use Mixamo's characters in games or images etc as long as paying attention to distribution rule.

But is it also generally allowded to modify the model, such as making a model shorter height, applying different outfit and colors, changing hairstyle..etc and use them under the same license?

I was a bit concerned, so asking here:)

Thank you!
