GoPro Deep dive with Bull shark, settings

I should have asked this earlier but I am diving Bull Sharks this afternoon at 3:00 p.m. currently overcast.

I have underwater filters and I also have lights but it's been my experience that u less they are at least 4 feet from me there is no point.

The filters will just make it that much darker to a already poor low light camera.

I could shoot in Protune and try and white balance later? But not sure what kind of noise adding Protune.

Low light mode worth playing with?

I'm taking multiple GoPros with me, two on my tray. One on a tripod and one on a GoPole. I've dove with the bulls before but it was much more shallow and better light.

Auto ISO limit is 1600.

The Hero6 (on tray) I'm setting up for 4k 30 fps with Stabilization. The Hero5 (on tray) I'm thinking 1080 at 120fps. Hero4+ (Tri-Pod) set at 4k 30fps. Hero4+ (GoPole) set at 1080 120fps.

Any tips would be appreciated.
