You can make bulk changes, such as changing the polling method, to nodes.

You can make bulk changes to nodes in NPM using the Manage Nodes feature. This allows you to select multiple nodes and edit their properties, such as the polling method, the polling frequency, the SNMP credentials, the custom properties, and more. You can also use the Edit Nodes feature to assign or unassign pollers to nodes, such as the Universal Device Poller (UnDP), the Hardware Health Poller, the Wireless Poller, and more12. References: 1: Change the polling method for a node3, 2: Manage pollers using Device Studio4
