You could get an If node and then an "Equal To" node. Then get a "Get Point ID" node, plug it to the First input of the Equal To, then in that node, set Second to the point index to look for. It will output a boolean (orange) output, which you feed to the Condition input of the If node.
Then in the If node, plug your logic to the True input instead of directly to the root icetree node. In other words, the grey execution plugs into the True input of the If node.
