Disable RTAV at the client instead of agent using GPO

I dont see this as a client option in the latest GPO bundle VMware-Horizon-View-Extras-Bundle-3.4.0-2769709.zip, ony an agent option.

We want RTAV on in the pool but off for certain clients. How can we accomplsh this? Enabling the policies "Exclude all devices" and disabling the policies "Allow Audio Input Devices, and Allow Audio Output Devices" is not having the desired effect. How else can we accomplish this?

I recommend having this ability in the client GPO's.
