What’s the shortcode you’re using there? I don’t think we really provide fine-grained options to remove pieces of the display there, though. Something like CSS Editor might be an option to just hide parts of the output, though.
We don’t really have options for that shortcode to change how those are displayed. The theme can control what’s shown for them (though the same code will control what’s shown for any images displayed as recent/featured on the default homepage).
You could use CSS in the theme or CSS Editor plugin to hide parts of the display you don’t want, also.
