Hello, @Trends Bird Limited,
Our theme provides three styles of the checkout page, which you can set by using the Advance Cart/Checkout Layout option under XStore >> Theme Options >> WooCommerce.
The available styles are Classic, Multistep, and Separated.
Unfortunately, there is no other way to change the layout of the checkout page, except through Customization or by using a third-party plugin.
Best Regards,
8Theme’s Team
