How would they do that? I'm sure you can buy some sort of aerospace component that has the signal integrity to do radios, but it sounds expensive. There's a reason these kinds of components (e.g. muxes) aren't usually physical disconnections.

Automotive power relays are at least a thing, but they're expensive consumables that have significant power draw.

In either case they would have had to add the components at design time and do the physical validation/testing, not ship it as a software update.
