No. Once you start the fight a gate closes and locks you in. After you defeat him the first time it unlocks the chest room (which you can farm with godsbane if you want) and you can then exit from there. The front gate where you initially entered the room remains closed.

The back exit is also a one way door, so once you leave the room, you can't get back without fighting your way back down.

On subsequent encounters he has 2 phases. The gate to the loot chests only opens after phase 2, so there is no way to only farm loot in phase 1.
