Back button focus on A7rIII. When not click any of the back button, I want to do manual focus

When not click any of the back button, I want to do manual focus. But I turn the focal ring on the lens. it does  not change the focal point. I assume nothing is triggering a auto focus and I should be able to turn the ring to focus. Did I miss a setting? I use auto tracking (for birding). Shutter is not doing any focusing.

My Canon R5 has the similar setup. When I do not press any back button that I setup. I can turn the focal ring on the lens to change the focal lens as if it is in the manual focus mode. Very convenient
