It cannot. Perhaps it would help if you explain the use case. Why do you need to include a layer (or not) depending on some variable? What would happen if you simply always include it? Can you create two separate build configurations, one with the layer, and another without? Generally it's a sign of badly written layer if merely including it causes unwanted side effects, and that's the problem that should be addressed. Alex
