Metabase via HTTPS using ACM

Does anyone have alternative instructions for setting Metabase up on AWS with an ACM certificate? The current instructions assume we have our own certificate and are using Route 53 which is not how ACM works. This is one area that AWS themelves is weak on directions.

Here’s where I found the current instructions that focus on Route 53. http://www.metabase.com/docs/v0.20.0/operations-guide/running-metabase-on-elastic-beanstalk
