Edit AWS SRP Auth Code to Set Custom UserAgent in C#

I am working on AWS SRP authentication code in C#. While the implementation is functional, it currently uses the default AWS SDK user agent, which leads to bans after some checks. I need a coder to set a custom user agent in the code. The solution can involve either directly editing the AWS SDK core or modifying my existing code to achieve this outcome. The goal is to ensure the custom user agent is successfully implemented.
