To remove the default store banner, you need to modify the template store-header.php.
If you want to do that, I can walk you through it.
However, you can change the default banner by going to wp admin > woocommerce > wc vendors > pro (scroll to the bottom of that page).
Your vendors should be able to add any store banner they wish regardless of what you have chosen as the default store banner.
They go to: pro dashboard > settings > branding.
