How do i make the bone CFrame rotate relative to the world?

I have an issue. i want the bone to rotate relative to the world and not the parent bone. When i play animation, the bone is rotating relative to its parent bone even when i set its cframe to aim at target and look at the target.

local c0 = script.Parent.RootPart["mixamorig:Hips"]["mixamorig:Spine"].CFrame
wait(3)
while task.wait() do
	wait()
	--print()
	local s =  script.Parent.RootPart.CFrame:PointToObjectSpace(workspace.target.Position)
	
	print(math.deg(math.atan2(s.X,-s.Z)))
	script.Parent.RootPart["mixamorig:Hips"]["mixamorig:Spine"].CFrame =c0* CFrame.Angles(0,(math.atan2(-s.X,-s.Z)),0)
end

It works except i want the bone to not be affected by the parent bones rotation.
