How to remove header and hooter on Auth block?

There is a common default header and footer are for all blocks (Products, Categories, Pages, Cart, Checkout, Order landing page, Homepage, Auth, 404)

I am editing ‘auth’ block. I want to remove header and footer for this block. There is a common message “This container is NOT used. Header container from the default location will be used instead. Set this location as default to use this container as header for all locations.”

How to remove them? Please advice.
