GDS ServerDoes KEPServerEX Support GDS? How to Manage Certificates for Multiple Clients Efficiently?

Hi Everyone,
I am very new to OPC UA Security Policies, currently using KEPServerEX and would like to know if it supports integration with an OPC UA Global Discovery Server (GDS) for managing certificates. Specifically, I have the following questions:

1. Does KEPServerEX support GDS? If yes, how can I set it up to work with a GDS to manage OPC UA certificates?

2. Certificate Management for Multiple Clients: I have hundreds of OPC UA clients connected to my server. What is the best way to manage certificates for these clients?

3. Handling Certificate Expiry: If multiple client certificates expire simultaneously, how can I manage this scenario effectively? Is there a way to automate the renewal and distribution of these certificates through GDS or any other method?

Any guidance, best practices, or step-by-step instructions would be greatly appreciated!

Thank you in advance for your help!
