If you want to change what is displayed based on the text “enrolled”, it is possible with JavaScript/JQuery, but not possible with CSS.  Also you can’t use localization either because that text (“enrolled”) is one of the standard labels used throughout the system (or you’d be changing it even in the admin screens).

Unfortunately Docebo doesn’t support injecting JS/JQuery into pages. The only way to do that is with an unsupported hack of one of the apps.
