Password protect certain products within ecommerce

Hi, does anybody know how to Password Protect certain products within e-commerce?

I have a Password Protected page https://www.scarablondon.com/scarab-club/scarab-london-preview which has various products that can only be viewed for 48hrs before they are released to the public. These products are controlled by filters as to where they will be displayed.

Thing is as each product is sharing the products template Green tourmaline & textured 18ct yellow gold stacking ring £3,250.00 these are now not protected.

Is there a way to add some code to tell the product page template to password protect when an item as the tag Scarab Preview?

kind regards
David
