There is no custom lightning master node in shader graph. I personally think there should be some custom lighting master node that is similar to the unlit graph. If there is no custom lightening maser node, I think an unlit shader should be used then you trying to implement a custom lighting model. (because it is the simplest master node).

Is there an unlit shader graph in Unity?
