To reduce opacity of both surfaces (a different way to say “To augment transparency”). I would guess 80% opacity for the upper surface and 20% for the lower should work, correctly representing the effect of clear waters.
Done that, the submarine would be visible at periscope depth, and disappear at a realistic depth.
There’s another possible solution, if I’m not mistaken.
Again: to reduce surface opacity.
Then, to place a continuous dark cloud under water surface.

Do you know how they were capable of showing under the water line of ships on IL2?

To my knowledge, if they can do that, they can do a ship that just go on that line and show it.
