Disable All Polling On A Node

Nodes can be unmanaged which will stop all polling. Here is a good example of doing this in bulk through using the API. https://thwack.solarwinds.com/product-forums/network-performance-monitor-npm/f/forum/41095/sw-powershell-bulk-unmanage-api-script let me know if this works for you.

I know they can be unmanaged but I still need to be able to change the status of the node manually and not have polling re-enabled.

Set the status you'd like the node to have via a custom property. I'd recommend a pick list to ensure there's never an issue typos. Then configure an alert ot change the status of the node based upon the custom property value. E.G. 'f custom property 'mystatus' = 'down' then trigger alert action to change the status of the node to 'down'.
