Win2k12 client; way to disable .NET 4 Framework

​Hello,​

​I'm planning on deploying Avamar 6.1 through SCCM, and was wondering if there is a way to disable the autodeployement of the .NET 4 framework (like an undocumented switch).​

​There is no way I will be allowed to automaticly deploy this component if the default is to push .NET 4 if it's not present on a system.​

​I understand VSS would not be supported then, but it may stil be a valid option for me.​

​Thank you for any tips/pointers.​
