Possibility a) Disable the regular service auth, something like:

service auth {
  unix_listener login/login {
    mode = 0
  }
}

and then just create the /var/run/dovecot/login/login socket yourself. You may need/want to do this for other auth-related sockets too.

Possibility b) Tell login processes to connect to your socket instead:

service imap-login {
  executable = imap-login newlogin
}
