Are you talking about the course completion status on the Course Overview block? That only appears if the courses in question have Course completion on. Also, in Moodle 4 I believe the progress bar has been replaced with a percentage number rather than the graphic.
The templates for this block are in /blocks/myoverview/templates and you can override these in your theme. https://moodledev.io/docs/guides/templates/#overriding-templates-in-a-theme
