Is it possible to programmatically disable a node? Scenario is I have multiple load cells connected to a Phidgets hardware interface. In node-red each loadcell has its own input node. Due to the data intervals that one of the load cells needs, I have found it only reads properly if the other input nodes are manually disabled. Not feasible to do that live. What I want is when I am on UI tab 1/sensor 1, the other load cell nodes are disabled. When I click on UI tab 2/sensor 2, it enables that node, and disables the others. etc. Only need to see one load cell values at a time. But the only way I see this being possible is if there is a way to programmatically disable a node, which I have not found.
Use simple gate and ui control.

Can be made simpler, but this flow i think will explain working better.
replace input-1,2,3 with your load cell input, and using ui-control you can replace open-1,2,3 inject nodes or use buttons in dashboard to trigger relevant inputs.
