It was hinted that he was somewhere in Florida at the time but I think he resisted the fated meeting with Pucci because he had the will of a Joestar, something the other three clearly did not have. Another viable reason could be that Dio's sons all share their father's attitude of wanting power and validation. Ungalo, Rykiel, and Donatello were losers so they were drawn to Pucci's promises. At the time of Part 6 Giorno already had full mastery of an OP Stand and was the head of a mafia empire so he had no reason to meet Pucci.
