To avoid unwanted disruptions from changes made by the Machine Config Operator (MCO), you can use the {product-title} web console to modify the machine config pool (MCP) to prevent the MCO from making any changes to nodes in that pool. This prevents any reboots that would normally be part of the MCO update process.
