Hi,
For this you would need to log a ticket with WooCommerce support.
Have you tried this: https://wordpress.org/plugins/woocommerce-checkout-manager/
You can also activate your child theme and use a function such as this added to your child theme functions.php
to remove certain fields:
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
unset($fields['billing']['billing_first_name']);
unset($fields['billing']['billing_last_name']);
unset($fields['billing']['billing_company']);
unset($fields['billing']['billing_address_1']);
unset($fields['billing']['billing_address_2']);
unset($fields['billing']['billing_city']);
unset($fields['billing']['billing_postcode']);
unset($fields['billing']['billing_country']);
unset($fields['billing']['billing_state']);
unset($fields['billing']['billing_phone']);
unset($fields['order']['order_comments']);
unset($fields['billing']['billing_address_2']);
unset($fields['billing']['billing_postcode']);
unset($fields['billing']['billing_company']);
unset($fields['billing']['billing_last_name']);
unset($fields['billing']['billing_email']);
unset($fields['billing']['billing_city']);
return $fields;
}
Cheers,
David.
