How to keep Texture Sample empty?

Hey guys,

How can I keep a Texture Sample empty ? For instance I want to create a master Material for further usage for instancing and I want to have an option for Normal map to use detail Normal Map over my Normal Map, but not always,
some times I want to leave in my instance this option not in use, just blank, so to keep normal map with no detail NM feature applied.

Is it possible or I have to create two materials with features for detail maps and without ?

Use a switch parameter and pass the texture smaple in through the true, and a vector3 (0,0,1) (default normal) through the false. Now you can chose with each instance if it uses detail normals or not at all.
