SEP 12.1.6 - Enable or Disable Features

Hi All,

          I have another question for you guys. I have been asked about enabling or diabling features in SEP. I have now upgraded to 12.1.6 MP1a. I know you can assign or change features in use on a client depending on which group it is in and if there is a Install package associated with it together with the list of features set to use with it. I have over 12,000 endpoint clients to deal with and quite a few have old 12.1 client installs. Can I just enable or disable the features with the SEPM without also installing the latest client package?

Thanks
