How to change default material when import FBX?

When import a FBX file,
imported material’s ‘Material Domain’ is set to ‘Surface’ and ‘Shading Model’ is set to ‘Default Lit’.

I’d like to change default value of ‘Shading Model’ to ‘Unlit’ automatically.

How can I do it?

Create base material with Shading Model “Unlit” and TextureSampleParameter2d instead simple TextureSample. Then import FBX, choose this created base material in Base Material Name (all drop down lists select Param or what you name in TextureSampleParameter2d).

All imported materials from FBX will be Instance Materials with shader model Unlit as in base material.
