The answer is… taratata!!!! :

function wpcodex_filter_main_search_post_limits( $limit, $query ) {
    if ( get_the_ID()==20 ) {
        return 'LIMIT 25, 10'; 
    }
    return $limit;
}
add_filter( 'post_limits', 'wpcodex_filter_main_search_post_limits', 10, 2 );

Because in 'LIMIT 25, 10';, here 25 is the offset and 10 the number of posts to display. So that way it will display 10 products beginning with the product 26…
