how to access ControlAPI of APISIX?

[mkyc]

I want to be able to monitor APISIX gateway deployment instance from my AWS ALB load balancer. I just want to monitor that gateway instance is UP, and not focus on specific routes. It looks to me that server-info plugin is perfect for that. According to documentation I need to access /v1/server_info endpoint from ALB. As far as I can tell from helm chart ControlAPI port (9090) is not exposed from pod and there is no corresponding configuration to expose it in apisie-gateway or apisix-admin services. Am I correct? Is there any possible workaround?
