I got the answer

Add below code in functions.php file

add_filter('post_link', 'postcustom_permalink', 10, 3);
add_filter('post_type_link', 'postcustom_permalink', 10, 3);
 
function postcustom_permalink($permalink, $post_id, $leavename) {
    if (strpos($permalink, '%winneryear%') === FALSE) return $permalink;
     
        // Get post
        $post = get_post($post_id);
        if (!$post) return $permalink;
 
        // Get taxonomy terms
        $terms = wp_get_object_terms($post->ID, 'winneryear');   
        if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0])) $taxonomy_slug = $terms[0]->slug;
        else $taxonomy_slug = 'no-year';
 
    return str_replace('%winneryear%', $taxonomy_slug, $permalink);
} 

and then after add %winneryear% in the custom permalink in backend.
