Not all hardware is digital.
RF design, radars, etc... are more an art than a science, in many aspects.
I would expect a Physics-trained student to be more adaptable to that type of EE work than a CS student...
Someone with a physics background might be better prepared for the analog world than someone with a digital background.
Not all hardware is digital but we can solve most of the hard parts in the digital domain. There's no reason to do everything analog just because it starts or ends that way.
A lot of RF design has been reduced to arrays of dumb antennas that are wired together in software. Starlink is probably the best example of this right now.
You still need people who can build the analog systems and engineer the nasty parts of the signal chain, but you don't need a lot of them.
