How to enable ENB terrain parallax onto a terrain texture?

[thegloriousargonaut]

Basically how do I make a terrain texture work with ENB Terrain Parallax?
Looking at various terrain parallax textures, they do not come with any modified .nifs or meshes.
Terrain Parallax from mods like terrain parallax tribute, just seem to magically work if you enable the terrainparallaxfix=true in your ENBlocal.ini and viola, parallax on your terrain textures.
They come with a regular .dds and a _n.dds and that's it, yet they seem to allow for terrain parallax. How? I literally don't understand how these magical terrain parallax textures are made or utilize the feature.
Basically I'd love for the terrain snow from Quality Snow 4k HD to support parallax terrain , but I have no idea how to modify the texture or normal maps to support the ENB feature.
Any assistance on this issue would be greatly appreciated <3.
