Not adjustable and the brakes aren't causing the rubbing sound. It's the tone ring behind the axle flange rubbing slightly on the axle tube...i just fixed same issue at left rear wheel on 2021 silverado...it still made same noise when cold with caliper and pads removed and does not have an internal e brake etc

Its not the parking brake or brakes at all...its the extrenal tone ring behind the axle flange rubbing on the axle tube....its a dumb design with minimal clearance and no dust seal...just fixed a 2021 with same issue still made noise with caliper and pads removed...primarily when cold
