I don't think the Giro is a good option next year because neither the Tour or the Vuelta would fit well in Pogačar's schedule.
If he does Giro-Tour he just risks arriving too tired to the Olympic Games and even if he is able to do a little peak for the Worlds+Lombardia, he likely wouldn't be at his best either. He would need to have a very light pre-Giro schedule too.
If he does Giro-Vuelta, he would arrive fresher to the Olympics but as Red Rick says having a Tour in the legs actually helps, at least for the road race. Plus, he would possibly ride Olympics, Vuelta, Worlds and Lombardia in little more than two months which seems just too much.
So next year, it really makes sense only to ride one Grand Tour and for the best rider in the world, who also rides several spring classics, that GT should be the Tour. The Olympics is just the cherry on top.
I think 2025 is the first year where there is a good chance of watching Pogačar at the Giro but that could also depend on the outcome of next year's Tour.
