Sorry John for this very long delay.

I used pre_get_posts hook for the archive page of my custom type, and change the post order by ACF field as below:

function legal_annonce_single_query( $query ) {

    if( is_admin() ) { 
       return $query; 
    }
 
    if(!is_admin() // Doesn't run on admin pages even though I have the above return
       && $query->is_main_query() // Cibler uniquement la requête principale
       && $query->query_vars['post_type'] == 'annoncelegale' // Actionner uniquement pour le post type Annonce légale 
    )

    {
        $query->set('meta_key','reference_al'); // ACF field Legal notice reference
        $query->set('orderby', 'meta_value_num') // / Sort by the specified custom field
        $query->set('order', 'DESC'); // / Descending order
    }
 }
 
 add_action( 'pre_get_posts', 'legal_annonce_single_query' );

But I can’t see how I can alter the query to return the correct post.
Do you have an idea ?
