Start and stop node execution

Hi all,

is the nodetree in geometry nodes always executed for all nodes or can a node be excluded from execution.?

You can mute a node, by pressing m on a selected node.

So if i try to develope a node to get a point stream from a depth camera there is a option to stop and Start the stream output.

In Animation nodes it was possible like that.

Since its jaques i guess its the same node execution design
