Until having a starlink terminal on your roof becomes punishable by death. You can try to hide them visually, but Iran could always detect them electronically if they want to put in the effort.
This is punishable and does get punished (rarely, I hear). Doesn't deter anyone.
Edit: it will also be quite difficult to detect electronically, judging by the fact that even Russia fails to jam these signals on the battlefield.
As for TX detection, you'd be surprised. Directional signals like starlink uplink are fairly hard to detect.
