Dojo: How to hide individual checkbox in CheckBox Tree

The cbTree is a Dijit Tree implementation with checkboxes.

While going through its API Docs there are some boolean properties of tree like leafCheckBox and branchCheckBox but those effects all the child nodes as well, i.e. if i set the leafCheckBox = false it hides the checkbox of all the nodes in tree.

So, is it possible to hide a single particular checkbox of a node, instead of effecting the whole tree?
