The avatar can accept additional bones, but the extra bones will not be animated. From your screenshot, it seems you mainly haven’t adjusted the pose to a T-Pose?
And, what do you mean by ‘create bones’? Humanoid should only use the bones you already have.
To my knowledge, Unity does not have a direct way to modify skeletal models. Unity’s model features always focus on convenience and speed. With Humanoid, you generally don’t need to pay much attention to the specific skeleton of the model. However, I guess there might be some packages that support this functionality.
