Conditionally hide or show woocommerce product variation in fontend by custom field

Question

I have added a custom field (checkbox) to product variations with the following code:

/**
* Create new fields for variations
*
*/
function variation_settings_fields( $loop, $variation_data, $variation ) {

woocommerce_wp_checkbox( 
array( 
    'id'            => '_wholesale_checkbox[' . $variation->ID . ']', 
    'label'         => 'Visa endast för företagskunder', 
    'description'   => '',
    'value'         => get_post_meta( $variation->ID, '_wholesale_checkbox', true ), 
    )
);

}
/**
 * Save new fields for variations
 *
*/
function save_variation_settings_fields( $post_id ) {

// Checkbox
$checkbox = isset( $_POST['_wholesale_checkbox'][ $post_id ] ) ? 'yes' : 'no';
update_post_meta( $post_id, '_wholesale_checkbox', $checkbox );

}

add_action( 'woocommerce_variation_options', 'variation_settings_fields', 10, 3 );
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );

It adds the checkbox as desired as seen in the screenshot.

Now I want to conditionally hide or show the product variation in the frontend based on this field. The problem is I have some custom variation list in place (not my work) and I couldn’t figure out how to get hold of the _wholesale_checkbox field to skip the variation (for which the checkbox is checked) in the loop that is outputting the list. See code for outputting the custom variation list below:

/**
 * Convert WooCommerce variation dropdown to radio buttons.
 *
 * @param string $html Original dropdown html.
 * @param array  $args Arguments.
 */
function ac_variation_radio_buttons( $html, $args ) {
$options   = $args['options'];
$product   = $args['product'];
$attribute = $args['attribute'];
$name      = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute );
$id        = $args['id'] ? $args['id'] : sanitize_title( $attribute );

if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) {
    $attributes = $product->get_variation_attributes();
    $options    = $attributes[ $attribute ];
}

// Output original dropdown element.
echo $html;

/* Create custom radio input list */
$html = '<section for="' . esc_attr( $id ) . '" class="ac_variation_list_block">';

if ( ! empty( $options ) ) {
    if ( $product && taxonomy_exists( $attribute ) ) {
        // Get terms if this is a taxonomy - ordered. We need the names too.
        $terms = wc_get_product_terms( $product->get_id(), $attribute, [
            'fields' => 'all',
        ] );
        // var_dump($options);
        foreach ( $terms as $term ) {
            /*
            if (**CUSTOM_FIELD is checked** )) {
                continue;
            }
            */
            if ( in_array( $term->slug, $options, true ) ) {
                $html .= '<section class="ac_variation_option">';
                $html .= '<input id="' . esc_attr( $term->slug ) . '_v" type="radio" name="' . esc_attr( $name ) . '_g" value="' . esc_attr( $term->slug ) . '" ' . checked( sanitize_title( $args['selected'] ), $term->slug, false ) . '/>';
                $html .= '<label for="' . esc_attr( $term->slug ) . '_v"><span></span>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term->name ) ) . '</label>';
                $html .= '</section>';
            }
        }
    }
}

$html .= '</section>';

echo $html;
}

add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'ac_variation_radio_buttons', 10, 2 );
