(typing off the top of my head, might not compile)

Since Unity 4.3:

In the shader, instead of writing Cull Off, write Cull [_MyCullVariable], the value will be fetched from the material or global float/int variable _MyCullVariable then.

You could have it be part of material, e.g. inside Properties block:

[Enum(Off,0,Front,1,Back,2)] _MyCullVariable ("Cull", Int) = 1

# Get all nodes of type Read
readnodes = nuke.allNodes('Read')
for readnode in readnodes:
    print readnode

# List all knobs for selected node
print( nuke.toNode('Read1') )
# List all knobs for specific node
print( nuke.selectedNode() )
