How to make http:dashboard listen only localhost: 18083

[JiapengLi]

dash board is listening at 0.0.0.0:18083, how to set it to listen on localhost only?
I would like to use nginx as proxy, and force it fully use https to access the dashboard.

emqx_ctl listeners
http:dashboard
  listen_on       : 0.0.0.0:18083
  acceptors       : 4
  max_conns       : 512
  current_conn    : 0
  shutdown_count  : []

neither of below configurations works
#dashboard.listener.http = "http://127.0.0.1:18083"
#dashboard.listener.http = "127.0.0.1:18083"
