Why isn’t random ordering working in pre_get_posts on WordPress?

I am working in WordPress and I am trying to order the product results randomly. Like every time a customer refresh the page then the products should be randomly shown. Currently no matter how many times I refresh the page.

Each time products are showing in the same order. The first product will be at first and last will be at last.

I am writing this query

add_action( 'pre_get_posts', 'rand_products');

function rand_products( $query) {
  
    //if ( ! is_admin() && $query->is_main_query() ) {
        $query->query['orderby'] = 'rand';
        $query->query['order'] = 'rand';
        $query->set( 'orderby', 'rand');
        $query->set( 'order', 'rand' );
    /}
}

If I see the query dump(attached in the screenshot) then I can see that query parameters have been changed but Still it is not working. Can anyone Please help.

    The troubleshoot might be coming from the fact that you’re using an undefined value for the order parameter.

    As per the WP_Query order & order by parameters:

    Parameters Values
    order (string | array) – Designates the ascending or descending order of the ‘orderby‘ parameter. Defaults to DESC. An array can be used for multiple order/orderby sets. ASC – ascending order from lowest to highest values (1, 2, 3; a, b, c).
    DESC – descending order from highest to lowest values (3, 2, 1; c, b, a).
    orderby (string | array) – Sort retrieved posts by parameter. Defaults to date (post_date). One or more options can be passed. rand – Random order.

    As you can see only orderby can take a rand value. order should be set to either DESC descending order or ASC ascending order.
