RF 70-200 IS always on?

With my RF 70-200 on an EOS R it sounds like the Image Stabilization is always on, no matter the position of the IS on/off switch. As long as the camera is turned on I can hear the motors in the lens. N o change in sound when I slide the switch on anad off. Is this expected behavior?

Are you sure that it is Image Stabilization? It could be this AF setting? Note the warning about turning off the camera.

I should have mentioned that I tried it with auto focus on an off. And I do not have continous focus turned on.

With auto focus on the sounds is more like a series of clicks and whirrs along with a constant smooth drone. With AF off it is just the droning sound.
