Are you traveling to Italy from abroad now? Yes, this is partly possible without requiring isolation. For example from Germany and Switzerland. The borders are passable! Note small formalities:
The region of South Tyrol is not on the quarantine list of Switzerland & the state of North Rhine-Westphalia, a negative test is currently required on the return journey. Medical trips, trips for health reasons and trips for professional reasons are possible beyond national and regional borders without, for example, the quarantine regulations applying to German guests after their return trip.
