WooCommerce related product - only show from primary category

Question

I have products in multiply categories

e.g. "All lamps", "Ceiling lamps" and "Black lamps".

"Black lamps" is the primary category (using Yoast SEO for making primary category).

My problem is that related products show products from all selected categories.

Is it possible to have related products only show from the primary category?
