if you like to animate everything modular, (that nothing has to do with nothing in the scene) like the head is not attach to the movements of the chest or the hands etc…

In the animate Rig go to the head select “ptr_ctrl_eyes_look_at” and check
“keep position when parenting” and then disconnect it from the rest of the tree.

like in the pic now when you move the head the eyes will not move with it. so you can move the head and then eyes to somewhere else

(you can also set a blen pose to have a slider and let the animator select what he wants)
