Trouble with "Please select" product option

-- HikaShop version -- : 4.4.0
-- Joomla version -- : 3.9.24
-- PHP version -- : 3.7.4

I am creating a product that has a few optional products added.

When adding an optional product that has no variants, the product page displays a "No" option in the dropdown to not include that item.
When adding an optional product with variants, you can only select from the variants. There is no "No" selection available.

I have looked at your demo, and on the Processor optional product, you have a "Please select" dummy variant included. I tried that, but when I add the items to the cart "Please select" is included in the cart as a shippable item. How can I exclude an item like that from being added to the cart?

That worked fine. Thank you.
