Starlink’s star trackers (left; used for precise pointing and positioning) and what are likely four gyros, also used for pointing and orientation. (SpaceX)

I don't think the satellites have cold gas thrusters, but there is one Hall effect ion thruster for orbital maneuvers (e.g. raising, lowering, phasing, station-keeping).

Question: What are the strategies that are available to the Starlink satellites for momentum-unloading of the control gyros?

Magnetic torque rods for desaturation of momentum wheels.
