You can add "Behaviors" to states in a controller, they're basically components. Use the VRCAnimatorTrackingControl behavior and disable tracking to the eyes & eyelids. You have to add the behavior to another state to restore tracking. You have to make a solution so these behaviors don't conflict with each other on each hand.
I make a new layer with two states that have no animation, it will transition to the state that disables tracking when any of the GestureLeft or GestureRight values are that of an animation that needs blinking disabled, and to return when all of them are inactive.
