By hitting Gyorg before dropping into the main room, you can skip the intro cutscene of the fight.
By damaging Gyorg next to the center platform, you are able to stunlock the first phase by swimming (with zora barrier) between Gyorg and the wall. The same carries into the 2nd phase, however now there are fish enemies swimming in the water as well.
Using Fierce Deity, you are able to damage Gyorg from that platform with sword beam stabs. This is useful for SRM categories that have Fierce Deity early.
