How to add a product without properties to the cart?

Question

1C-Bitrix

Good evening!
On the site of a different category, goods are clothes, shoes and shoe care. The product on the site is stored without trade offers, I display the catalog with the complex component Catalog. The product has many different properties and they all differ, but one is set for all of them - this is Type, it is set to multiple in the infoblock settings, which makes it a drop-down list on the product’s haircut, if you make it non-multiple, the Type property disappears from the component settings from the Add to Cart section, so for the product, it ceases to be displayed on the page. Such a product as shoe care has no size and when adding it to the cart, an error is generated: not all properties are selected to be added to the cart.
Tell me how to make it so that the product without properties gets into the basket?
Allow adding to the cart products that do not have all the characteristics specified
Or how to make the Type property not be displayed but displayed in Adding to cart?
