Culling of faces

Hello! I woud like to know if there is a way of activating and deactivating culling of faces in a geometry without using the script.(without writing a script)

You would do it through a custom shader, i.e.

...
Properties {
...
[MaterialEnum(Off,0,Front,1,Back,2)] _Cull ("Cull", Int) = 2
...
Subshader {
...
Cull [_Cull]
...
