I am not aware that there is already a Policy for this.
Do you know if this option results in a specific registry key on the client?
Maybe you already know which key?
If not, a general approach woul be to monitor registry activity via Sysinterals's Regmon:
http://technet.microsoft.com/en-us/sysinternals/bb896652.aspxBy setting or unsetting this option while running the tool you should be able to determine the correct registry key and value.
With this knowledge, you can either create a ADM template to deploy this via GPO or, more fancy since Windows 2008, use GP Preferences and
the "Registry" extension to deploy the desired registry value. Of course, for GPP you have to fullfill some prerequisites (CSE installes on client,
1 management station with W2K8 or Vista).
Though this is no final solution I hope it gives you some ideas about the possibilties...
