Allow insecure connection to Supabase

[UBy]

Could we get an environment variable for overriding security on the Supabase API connection - for example ALLOW_INSECURE_SUPABASE_CONNECTION?
It would make it so much easier to connect by docker service name, e.g. http://kong:8000.
it seems to me that any hostname that is not localhost is considered external and requires ssl.
A variable to allow a self signed supabase certificate could also make it work.
