posts_orderby exclude section from sorting

Hi, I use this code to sort the products randomly:

session_start();

add_filter( 'posts_orderby', 'misha_rand_order_with_seed' );
 
function misha_rand_order_with_seed( $orderby_statement ){

    if( !is_shop() && !is_product_category() ) return $orderby_statement;

    $seed = $_SESSION['seed'];
    if (empty($seed)) {
      $seed = rand();
      $_SESSION['seed'] = $seed;
    }

    $orderby_statement = 'RAND('.$seed.')';
    return $orderby_statement;
}

how can I make sure that the row of products located right above the footer is not affected by it? I mean the 6 squares at the bottom of the page, it’s a Portfolio widget from the Elementor plugin. Thank you.
