Hello,
You may wait for the next release where it will be included globally. Also, you may copy only a few files to your production ->
1/ xstore/woocommerce/checkout/form-checkout-default.php
2/ xstore/woocommerce/checkout/form-checkout-multistep.php
3/ xstore/css/modules/woocommerce/pages/cart-checkout-advanced-layout.min.css
4/ xstore/css/modules/woocommerce/pages/cart-checkout-advanced-layout.css
Regards
