The first thing to remember is that the server will (with only a couple of exceptions) only send options the client asks for, so check if the client is asking for it. Network sniffers like Wireshark are useful for this.
It’s possible to force the server to send an option the client didn’t ask for, but ...

If the client isn’t expecting and option, or doesn’t know how to handle it, then it’s unlikely to have any effect.
I have a rather vague recollection of discussions around this option here in the past - and vaguely recall that most clients neither request it, nor know what to do with it if it’s sent.

So :
Does the client ask for the option ?
If it does, is it being sent by the server ?
If it’s being given the option, does the client actually know what to do with it ?
