Answer 1

You can set for node userNode.setSelectable(false) and in jsf treetable add

showUnselectableCheckbox="true"

Answer 2

I found a solution for this. But is not elegant, this can be done with css, We can add a conditional css to the tree and make it unclickable.

    .not-clickable {
    cursor: not-allowed;
    pointer-events: none;
}

Used above css style in the tree with a condition,

<p:tree id="tree" styleClass="#{not backingBean.editable?'not-clickable':''}" cache="false" value="#{backingBean.treeRoot}" var="node" selectionMode="checkbox" selection="#{backingBean.selectedValuesNodes}">
