What does "Hybrid instanced" in shader graph do?

In the shader graph editor, in the shader blackboard, there are tick marks labeled Hybrid instanced (experimental)

What does it do?

This is a feature that allows the shader to be used with the Hybrid Renderer package, which is what you use for rendering entities in DOTS. See the docs:

https://docs.unity3d.com/Packages/com.unity.rendering.hybrid@0.4/manual/index.html

Any answer for this?
