I'm going to go ahead and post a solution to this, which was provided by Moonami tech assistance. Somehow I did not come across this on other, but apologize in advance if this is out in the open somewhere.
This solution will allow Section-0 to show on ONLY the main page of your course; not in the topic sections.
Within the Boost theme settings (Admin Settings > Appearance > Themes > Boost >Advanced Settings), simply paste the Raw CSS code below in the box designated Raw SCSS (NOT Initial Raw SCSS).
body#page-course-view-grid .gtopics #section-0{ display: none; }
I hope this helps some of you out there who want a cleaner layout.
