how to Disable Node at Runtime in Fusion

Hi, If I want to disable a node, not in EDIT MODE, in runtime. I want the node to DISAPPEAR in any specific point in time, how to do it? Here's one point, I dont want to change the size or blend/opacity of any node so that it doesnt show up, bcoz this way they are not completely gone, there actually INVISIBLE from the view, I want to completely deactivate a node in Fusion, so that it doesnt take resource after a specific time. For instance how to REMOVE A TEXT NODE after a specific time (not making it invisible, completely disable/deactivating the node).
