Flying to Italy and having trouble going through registration process for my drones. How strict are they at customs?

Flying into Italy this week and I’ve left part of this quite late.

Trying to get registration of my drone but the ENAC website has not yet processed my ID yet. Is there any way to circumvent the website? Can I register my drone when I arrive in Italy before I fly it?

Do they check details at customs? Flying into Rome
