There is no such thing as .NET Framework version for specific IIS module , Isapi and CGI Restrictions in your case. The menu item refers to global .NET Framework version setting in IIS (same you see in the right-side action panel on the first screenshot). In fact, the setting controls what version of the framework to assign to an application pool when you create one. You can use the following command:

appcmd.exe set config -section:system.applicationHost/applicationPools /applicationPoolDefaults.managedRuntimeVersion:"v4.0" /commit:apphost

When you execute it all new application pools will have .NET Framework 4.0 assigned. However, on my box the setting in the dialog from second screenshot remains 2.0 (looks like UI/usability bug to me). See this for more details.
