Iveth,
I'm assuming you mean the social buttons (like, share, +1, etc) and not login functionality for those other networks. We currently don't have a module that has enable/disable options for each of those. However, you can easily add the following tags to a Custom HTML module and have the same effect:
{JLinkedShare}{SCGooglePlusOne}{JFBCLike}{SCTwitterShare}The custom HTML module will also let you wrap those in HTML so you can format where they land however you want. For more information on those tags, and the options available for sizes and looks, see:

Hope that helps,
Alex
