It isn't about blocking anything, remote attestation confirms the system is in a particular configuration, but it doesn't actually block you from doing anything you want. The "locked down" part just means that running any unapproved programs or system configurations would lock you out of the game. So as long as the game servers recognized discord as an approved program you could run it while connected to game servers.

Yeah, playing an audio book in the background while I game is my default mode of play now.
