I learned from a BSides presentation that Ukranian military are using Starlink trancievers placed in pits to beat ground-based signal detection. Do with that what you will.
google image search "iran confiscates satellite dishes" for some example photos from their domestic media.

There's also the problem of just physically identifying starlink terminals on roofs. Iran has gone on sprees of confiscating ku band TVRO satellite dishes for a long time.
It's entirely possible to use a starlink terminal with exclusively wired ethernet stuff, including usb-c to gigabit ethernet adapters plugged into android phones, it just takes some training and discipline for the ordinary non technical user.
But this is also an example of weird absolutist thinking about military tactics: is it unbeatable? No. Does it complicate the surveillance and detection picture? Yes.
