Hello Mike, thanks for the follow up. Found a way to ‘disable’ the theme and use the core wc template.

This code do the trick:

functions.php

function custom_checkout_template($template) {
// Check if it’s the checkout page of WooCommerce
if ( is_checkout() && ! is_wc_endpoint_url() ) {
// Path to your custom template file
$custom_template = locate_template( ‘checkout.php’ );

// If the custom template file exists, use it; otherwise, fallback to the original template
if ( $custom_template ) {
$template = $custom_template;
}
}

return $template;
}
add_filter(‘template_include’, ‘custom_checkout_template’);

Then we can use in the theme checkout.php

<?php
/**
*
* @see https://docs.woocommerce.com/document/template-structure/
* @package WooCommerce\Templates
* @version 3.5.0
*/

if ( ! defined( ‘ABSPATH’ ) ) {
exit;
}

$checkout = WC()->checkout; // Instantiate WC_Checkout class

do_action( ‘woocommerce_before_checkout_form’, $checkout );

// If checkout registration is disabled and not logged in, the user cannot checkout.
if ( ! $checkout->is_registration_enabled() && $checkout->is_registration_required() && ! is_user_logged_in() ) {
echo esc_html( apply_filters( ‘woocommerce_checkout_must_be_logged_in_message’, __( ‘You must be logged in to checkout.’, ‘woocommerce’ ) ) );
return;
}

?>

<form name=”checkout” method=”post” class=”checkout woocommerce-checkout” action=”<?php echo esc_url( wc_get_checkout_url() ); ?>” enctype=”multipart/form-data”>

<?php if ( $checkout->get_checkout_fields() ) : ?>

<?php do_action( ‘woocommerce_checkout_before_customer_details’ ); ?>

<div class=”col2-set” id=”customer_details”>
<div class=”col-1″>
<?php do_action( ‘woocommerce_checkout_billing’ ); ?>
</div>

<div class=”col-2″>
<?php do_action( ‘woocommerce_checkout_shipping’ ); ?>
</div>
</div>

<?php do_action( ‘woocommerce_checkout_after_customer_details’ ); ?>

<?php endif; ?>

<?php do_action( ‘woocommerce_checkout_before_order_review_heading’ ); ?>

<h3 id=”order_review_heading”><?php esc_html_e( ‘Your order’, ‘woocommerce’ ); ?></h3>

<?php do_action( ‘woocommerce_checkout_before_order_review’ ); ?>

<div id=”order_review” class=”woocommerce-checkout-review-order”>
<?php do_action( ‘woocommerce_checkout_order_review’ ); ?>
</div>

<?php do_action( ‘woocommerce_checkout_after_order_review’ ); ?>

</form>

<?php do_action( ‘woocommerce_after_checkout_form’, $checkout ); ?>

And from there, it could be customized as needed.
