Repeatable fields can be stored in an array using PHP, and using the PHP shuffle() function, we can shuffle the array elements.
$customer_reviews = get_field('customer_reviews');
shuffle($customer_reviews); // magic happens here :)
if( have_rows('customer_reviews') ):
foreach( $customer_reviews as $customer_review ):
$review_title = $customer_review['review_title'];
$review_description = $customer_review['review_description'];
$review_star_ratings = $customer_review['review_star_ratings'];
echo '<h2>'.$review_title.'</h2>';
echo '<p>'.$review_description.'</p>';
echo '<strong>Stars: '.$review_star_ratings.'</strong>';
echo '<hr>';
endforeach;
endif;
