Hi,

The setting is not available to customize the default contact form.

If you don’t want to use this default contact form, you can install and use Contact Form 7 for your contact page
https://wordpress.org/plugins/contact-form-7/

To remove the Contact Form from main right sidebar
Go to the Appearance -> Widgets -> Sidebar Main -> Add Widget

Please check the documentation
