Removing header on a page

I have a page that will be available for everyone to see (non-logged in users). It is a simple email opt out page where a person will be asked their email to opt out. I don’t want this page to show my normal non-logged in user header which has a sign in button. (No need to confuse anyone that they can sign in). Is there a way to suppress the header on that page?

Yes there is an option to suppress the header or footer from any page:

Thanks, can’t believe I missed that.
