Sorry Not really a great answer. However, I haven’t got enough Reputation points to add a comment yet 🙁
I was just reading this site, and I saw the following snippet that could be useful for what you are trying to do.
(this is not my code I use this page for a lot of great ideas & tips)
/**
* @snippet Simplify Checkout if Only Virtual Products
* @how-to Get CustomizeWoo.com FREE

*/
add_filter( 'woocommerce_checkout_fields' , 'bbloomer_simplify_checkout_virtual' );
function bbloomer_simplify_checkout_virtual( $fields ) {
$only_virtual = true;
foreach( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
// Check if there are non-virtual products
if ( ! $cart_item['data']->is_virtual() ) $only_virtual = false;
}
if( $only_virtual ) {
unset($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']);
add_filter( 'woocommerce_enable_order_notes_field', '__return_false' );
}
return $fields;
}
I hope you find it useful 🙂
