How to disable categories?

Question

WooCommerce

There is a standard cycle for displaying posts (in this case, products)
In archive-product.php I display products

<?php do_action('woocommerce_before_main_content'); ?>
    
        <?php do_action('woocommerce_archive_description');?>
        
        <?php 
        
        $args = array(
          'post_type' => 'product',
          'posts_per_page' => 19,
        );
              
        global $wp_query;
        
        $wp_query = new WP_Query($args);
        
                
        if($wp_query->have_posts()) :
        ?>

        <?php woocommerce_product_loop_start(); ?>
          
          
          <?php while($wp_query->have_posts()) : $wp_query->the_post(); ?>

            <?php wc_get_template_part('content','product');?>
            
          <?php endwhile; ?>
          
        <?php woocommerce_product_loop_end();?>	
        
        <?php endif;?>
        
        
    <?php do_action('woocommerce_after_main_content');?>

In this case, products and categories are displayed, but how to display only products?
