Hello!
When adding a product, check the "Sell individually" box in the "Inventory" tab

Maybe someone will need this:

/*человек добавляет в корзину товар А. Ходит по сайту и через какое-то время добавляет товар Б. При этом товар А должен автоматически быть удален из корзины.*/
add_filter( 'woocommerce_add_cart_item_data', 'my_empty_cart_before_add', 10, 3);
function my_empty_cart_before_add( $cart_item_data, $product_id, $variation_id )
{
    global $woocommerce;
    $woocommerce->cart->empty_cart();

    return $cart_item_data;
}
