Use the ALB for rack API

I noticed there is still a classic load balancer attached to each rack… Is it possible to configure the rack somehow use the ALB for the rack API?

I see similar words about this here: https://github.com/convox/rack/pull/3218/files. But the rack param defined in that PR isn’t part of the rack param documentation (https://docs.convox.com/reference/rack-parameters). So I’m not sure if it is a real thing or not.
