How to remove the default Woocommerce category?

Question

WordPress

If I don’t need a category at all on some products, how can I disable the assignment and display of the category by default? (And also, if you know how to do it, if I don’t need a price for a certain product, it goes on order, I remove the price, there is no buy button, how can I make it possible to order without showing the price for some product?)

Although late, but still, suddenly someone will come in handy. Can be done with a hook:

add_filter( 'option_default_product_cat', function( $value, $option ) {
  return false;
}, 9999, 2 );
