How to use kong.conf with Kong Ingress Controller

I want to setup an ssl certificate for my kong ingress controller & for that, I guess I need to make changes to kong.conf file.
Can anyone tell me where should I look for the kong.conf file in my cluster and how to make necessary changes to enable ssl for ingress controller?

To remove any ambiguity, could you confirm if you are trying to enable SSL on the Admin API of Kong?

If yes, it will be done so using environment variables for the pod.

Please take a look at our Helm chart for reference:
