Updated October 23, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Advanced configuration options for DEX cover agent proxy and connection settings, agent and application source conversion, sudo banner validation, device user mapping, and location determination. You can use these options to
fine-tune system behavior for specific organizational requirements.
* **[Configure ACC to use a proxy for all traffic](https://www.servicenow.com/docs/xhRO5JM9g84a7pq_r4yTeA)**   
  Configure the Agent Client Collector (ACC) to use a proxy for all traffic by setting environment variables.
* **[Switch ACC from one instance to another](https://www.servicenow.com/docs/GUCVX4~JC7Kh0kMcNXLULw)**   
  Switch Agent Client Collector (ACC) to a different instance.
* **[Configure MID-less Agent Client Collector using a single-line command](https://www.servicenow.com/docs/kbYoTch1bDt9Dbue6c8vLQ)**   
  Use a single-line command to set up a MID-less Agent Client Collector. You can also use the single-line command to migrate agents configured with a MID Server to have a MID-less configuration.
* **[Convert MID-based ACC to MID-less](https://www.servicenow.com/docs/7tVWU0WF~nHHjBPqdiwvDQ)**   
  Convert MID-based Agent Client Collector (ACC) to MID-less ACC by adjusting the configuration in the acc.yml file so that ACC doesn't depend on a specific MID Server.
* **[Convert an application source to DEX](https://www.servicenow.com/docs/enL3r5EiJB~7ya64mChhUQ)**   
  Convert a Visibility Content application to DEX monitoring. After conversion, the application is managed in the Application and Device Health system.
* **[Sudo banner validation](https://www.servicenow.com/docs/5uvSFpjTl41~Wl4Zy0A7CA)**   
  Sudo banner validation flags missing sudo permissions on managed devices so you know when the DEX agent's capabilities are limited.
* **[Map a device user to a ServiceNow DEX user](https://www.servicenow.com/docs/CRxqNPj32Fl9OWx7GRPhSw)**   
  Map a device user to a DEX user so you can notify the user when device metrics breach a predetermined threshold.
* **[Device location determination](https://www.servicenow.com/docs/KxUlYVQEFyK4jczLXZURnQ)**   
  Device location determination identifies the number of impacted devices at each location based on configurable logic.
