First, put your AK day as far towards the end of your trip as possible. A 9am may not be available, so you may have to plan around that.
If you get there at rope drop (for NRJ I’d still say at least 30 min early), and they continue to let people in early, and you get the 9am FP, then I’d say you’d finish around 9:30. It does take time to get thru the ride, with 2 pre-shows and a long queue (even the FP side).
But do make sure you make time to just wander around Pandora; if you want to get on rides with low waits, then come back later in the afternoon. But the whole area is so detailed and great to see.
