How do load Adobe Plugins in Adobe Reader DC

I am puzzled regarding how to load Adobe plugins that are listed in the Digital Edition Help menu selection "About Adobe Plugins".  The info window for this topic shows a collection of Adobe Plugins that (I guess) came with my install of the software.  But some of them are shown as loaded and some are shown as not loaded, such as the DRM plugin for example.  Some of them seem to be loaded at some times but not loaded at other times, and there is no control or function that I can see .that provides this functionality.  I cannot find any info on how to find, load, unload, actyivate, or whatever in the Help files.  The list is pretty long and most are loaded, but I would like to now where to get plugins, how to install and activate and control them, and so on for the DC reader so that I can control what is available etc.  Any help would be appreciated.

This reader is the greatest PDF reader for my Win desktop PC ever, I wish there was a version for my Android tablet that was as marvelous and as functionable as the desktop version....
