  There is no way to do that in RADIUS.  No RADIUS client supports it.

  There is experimental code to do it, but again... no RADIUS client supports it.

  Even if you did manage to send a CoA packet down a TLS connection, the client would just ignore it.

  What you want to do is impossible, and won't work.  The clients have to be updated to support this.

  We don't need to see configuration files.

  You have to specify a "home server" of type "coa" in order to send CoA packets.  This is documented in proxy.conf.
