You can configure the update behavior on the Endpoint Agent that resides on managed devices. This includes if a dialog box displays on the managed devices prompting users to allow the system update or a required boot after a system update is applied. Users can either postpone the update or reboot. You can also provide custom text in the prompts that you choose to display.
For more information, see Configuring the Agent Update Behavior of the Endpoint Agent
in the Endpoint Management Agent Updates Reference.
