How can I turn off the linkage reaction of joints?

I have a question about writing a plugin. When I rotate a joint of the avatar such as Caleb.iAvatar, I found that some other joints also rotate a little bit. Here is an example:
This picture is a side view of the avatar, which is in T-pose posture. The whole avatar is straight.

When I rotate his left thigh, his whole body move down and forward a little bit, and his right knee is bent a little bit. I show the changes in parts of his body with red arrows in this picture. Hope you can understand what I say.

Is it a FK or IK properties of the avatar? I want to program to rotate only one joint and keep the others in their original position. To turn off the linkage reaction of joints, which API should I use? I had tried RLPy.RIHikEffectorComponent.SetActive(), but it seemed nothing happened.
