[xwiki-users] Disable applications for users

I am running XWiki version 6.2.2 (the latest available Ubuntu package). As you will have gathered from my other posts I am still new to XWiki. One of the packages included by default is the Blog application. I have no need for this in our organisation and I would prefer to exclude packages that I do not wish to support. But when I try to remove the package I find that I must also remove "XWiki Enterprise - UI - Main wiki<https://alertnessdb.net/xwiki/bin/admin/XWiki/XWikiPreferences?exte… which sounds pretty important. As a side point I'd like to suggest that this dependency be removed, since I don't see why a wiki must contain a blog application. My main question is how do I remove this application from sight? In particular it appears in the applications panel, so is there a way to deactivate this simply?
