How to do this type of operation in Houdini to layer material, instead of using mix shader.

In short , assign multiply material to the same prim, and use opacity channel to control the visibility.

You could use the material mixer node, but in Octane 2020.2 you also have the material composite node, that supports multiple material layers.
