Thanks for reaching out and posting this question!
I understand that you're looking to remove the Shop Now button from the header. While I'm unable to view your website and see how the button was set up, it's possible that the button was simply added as a menu item to the header. You can try removing the button from the header through the Navigations of your Online store, and we also have a guide on that here: Menus and links.
I noticed that you're a new member of our Shopify Community! Once you've removed the Shop Now button, I'd love to hear more about your business and share some resources to help you get started. What types of products are you looking to sell? Do you have a marketing plan prepared for your store?
