Is there option in exporter to disable it?

Not really, you can not have a single vertex with 2 different normals (i.e. a vertex shared between two different flat faces).

The displacement shape could have an option to consider overlapping vertices as one vertex for the displacement step.

From what I know, Cycles can adaptively tessellate each face of a mesh depending on camera distance.
Dade's example shows something similar, but it currently works per whole mesh, not per face.
So for example, with Cycles you could use one huge plane for the pebbles image you posted, and the parts of the plane that are close are tessellated more than the parts of the plane in the background. Lux currently would tessellate the whole plane uniformly.

Hey Guys. i'm a bit lost with Luxcore displacement.Want to know if our displacement method is still per whole mesh or per face adaptive like cycles one ?

When using the Subdivision node in combination with the Height Displacement node - is there a way to keep the smooth shading of the surface?

I have a different question, I can not find any documentation about displacement and parameters in the wiki!

Some information about this issue as well?

Smooth shading is preserved

Here's a comparison with and without displacement.

Here are the nodes.
