2021 Chevrolet Silverado 1500 LTZ 6.2 — anyone else: Silverado light-throttle shudder: engine or transmission?

At steady speed with light throttle I get a vibration that feels almost like driving over fine rumble strips. It disappears if I accelerate. What's the cleanest way to separate wheel/tire issues, cylinder-deactivation behavior and converter/transmission shudder?
