delete redirect mailchimp

hello,
if i usse this plugin with mailchimp it redirects me to a confirmation page. I’ve seen i can delete the confirmation with this link https://kb.mailchimp.com/lists/signup-forms/design-and-host-your-own-thank-you-pages and i can redirect to a custom page. But can i delete the redirect and so use only a ‘thank you’ message under the from without redirect? thanks
