How can I hide the ‘Add to Cart’ button on specific products?

add_filter('woocommerce_is_purchasable', 'wpsc_hide_add_to_cart_button_on_specific_products', 10, 2);

function wpsc_hide_add_to_cart_button_on_specific_products($is_purchasable, $product) {
    $hidden_product_ids = array(27, 28); // Add your specific product IDs here

    if (in_array($product->get_id(), $hidden_product_ids)) {
        return false;
    }

    return $is_purchasable;
}
