How to start with a simple version, ie. no Tasks, no Friend, no Badge, no Followers capabilities

Hi

I am preparing the switch to our new Easyxxx website.
My users come from an old website with just forum, articles and event mgt.
I would like to start with the same scope then I will introduce Friend/Badge/Tasks capabilities later (or not!).

My question is: how can I disable (unpublished?) the features : Friend, Tasks, Followers and Badge in EasySocial, EasyBlog and EasyDiscussion?

Is it easy?
Do you recommend to do it?
