Final answer:
It is false that you need to remove the additional_checkout_buttons Liquid tag to display offsite gateway buttons on the checkout page; these options are managed within Shopify's payment provider settings.
Step-by-step explanation:
The statement is False. If you want to display offsite gateway buttons on your checkout page, you do not need to remove or comment out the additional_checkout_buttons Liquid tag from the cart page. In Shopify, the additional_checkout_buttons tag is typically used to include third-party payment options on the cart page and has no effect on the display of these buttons on the checkout page itself. To show or hide different payment options on the checkout page, you would need to configure your payment provider settings within Shopify's admin panel.
