Modules I'm not using still installed during version updates

Since using the current update for EasyBlog through either the Component's update link or in Extensions > Update, now all modules I don't use are installed anyway and show up in Extensions > Discover. Is this intentional? I'd like to keep my Joomla! files lean and only have on the server what I'm actually using. That means with each update I have to manually delete the files for each module / plugin I don't want. Is there some way to prevent this in the future?

Joomla 3.8.12
EasyBlog 5.2.9
