CyberMag Theme How to Take Image Off Home Page

Hi ya’ll. I am not an expert at WP but I do know how to add and delete some stuff in the editor.

I am using CyberMag theme at https://smallbusinesspromote.com and I want to take the images of those three computer screens off the home page completely, I guess I am afraid I’m going to screw things up with a trial and error. Can someone tell me how to do this?
