How to remove Header Image Section

Hello, I have the Cact Vogue Premium theme. How can the Header image be removed? In the Theme FAQs it says: Header Image "Custom Header Image is different from site logo. It’s a large global image in the header to obtain a much more personalized look and feel. To add header image, you need to go to “Appearance => Customize => Header Media =>Header Image”. Here, you can add/change/hide Header Image, select option to Enable Featured Header Image on, Size and add in links and alt tag as per your website need." But those options--add/change/hide-- don't appear in the Theme Options. I can change the sorting, but can I hide/disable it altogether? Can it be it be hidden with CSS? --Evan
