Bake normal map for vector displacement map?

I am using vector displacement maps to create a shape out of a plane. I need a vector displacement map because this allows me to create overturning waves. However, for the shading to be correct, I will also need a normal map that goes together with the VDM.
See example in video here:

The normal map i have baked is full of problems and does not result in correct shading.When baking the normal map, evidently there are problems where the crest of the wave overlaps.

Can anyone help me?

You will need to transform your normals according to the displacement you’ve done. This is typically calculated on vertex shader using custom UVs.
