Not all.

AFAIK the spray-in bedliner is a physical component.

Tonneau cover, depends on the model. Mine, there was a slight delay, but FWIW was a 'rolling' (i.e. no electronics) style.

Mud flaps, pretty sure are not electronic.

As another 'ancillary' item, wiring harnesses have been hard to come by, which has an impact on both ICE and EVs. Electronic, but not a silicon supply constrained component per se.
