Earliest Disembarkation time in Civitavecchia

[IECalCruiser]

We will arrive in port at 5:00 in the morning. In U.S. ports disembarkation doesn't start until around 8:00 but on our Baltic cruise disembarkation started around 6:00. For those who have disembarked in Civitavecchia recently, what time did disembarkation start? Not trying to make a flight but looking at scheduling a Vatican tour as the next day is Sunday.
