Sorry to say but the Theme uses the default WooCommerce Templates for Cart and Checkout pages, for which you can create Custom Layouts using the Theme’s Layout Builder (https://xtemos.com/docs-topic/woodmart-woocommerce-layout-builder/) but that specific mentioned request of yours requires Customization as there is no option in Theme Settings available for that. This is beyond our limitations and Support policy scope. Hope you can understand our limitations.
Although, regarding the Account creation option on the Checkout pages, you can check out the options available under the Dashboard > WooCommerce > Settings > Accounts & Privacy tab > there you can find those: https://ibb.co/Mn93Bxm
