Yes, this request is directly related to the challenge I'm currently experiencing.

I'm deploying and using AWS Bedrock services in an enterprise environment, but due to our company's network security policies, all external AWS service access must go through the company's proxy server. Currently, the system doesn't allow configuring a custom Bedrock endpoint URL, which prevents us from properly connecting to the service.

Specifically, the challenges are:

1. Company policy requires all outbound traffic to go through corporate proxy
2. Default AWS Bedrock endpoints are not directly accessible
3. Need to use specific internal endpoints to ensure compliance and security

I believe other users working with this service in enterprise environments might face similar situations. Adding the bedrock_endpoint_url configuration option would help resolve this issue, making the system more flexible and adaptable.
