Import Instanced GEO in USD Payload as Nanite?

I am using Houdini and USD to create my layout and scene. How should I go on enabling nanite on geometry like scattered trees and rocks and bushes ? I know I can enable the option but can i instead drive that with an attribute from Houdini ?

If this is currently not implemented, can someone direct me to a python or automation workflow to loop over each object to enable the tickbox and hit apply ?

I am quiet familiar with python.
