Cover Options / Homepage

Hi, My website is silviafdez.art I'm customizing my home page and I just want to show the header image and my portfolio. But in theme customization > theme options > cover options / homepage, it forces me to show my recent posts, but I don't have any posts, so I don't want that to show up on the home page. The problem is that, as I don't have any post, the message "nothing found" appears on the home page, and I can't remove it. Is there any way to fix it? Thank you.
