Water_Material_Ocean - not able to control depth transparency of water

Hi there, I’m using UE 5.0, and have the standard WaterBodyOcean setup with the standard Water_Material_Ocean shader. My goal is to create a realistic look of how a boat would look partially submerged in a deep ocean. In the render, the part of the box that is submerged is perfectly visible, whereas I’d like for it to not be visible at all, as the ocean is murky and very deep. It would show some reflectivity of the boat and environment from above, but not allow for the the entire submerged body to be visible. …not like a swimming pool or shallow body of water. Does anyone know which controls would allow for limiting the transparency of elements that are submerged…some sort of depth control… I’ve looked everywhere. Any thoughts would be very helpful!!
