Hi Hytec Power Inc, thanks for reaching out. Unfortunately, the option to completely delete a course from the portal is currently unavailable. However, our team is actively working on adding this feature in the future. In the meantime, to prevent others from accessing the course, you can turn it offline. Change the course title with prefix X_ or Closed_ to indicate the course is not being used. 

By the way, we also have responded to your chat regarding the same topic. Hope this helps! Have a great day ahead!

Hytec Power Inc also, if you maybe want to use the same URL, what we can suggest is, simply delete the current course content and replace it with your new material.
