How to query posts from other lang?

Im using this snippet to disable translations in Blog posts:

function turn_blogposts_translation_off( $post_types, $is_settings ) {
  unset( $post_types['post'] );
  return $post_types;
}
add_filter( 'pll_get_post_types', 'turn_blogposts_translation_off', 10, 2 );

I have site with two lang – PL and EN, and Blog posts are only in PL lang. I would like to query PL Blog posts in EN version. So I need to use in query:

$args_menu = array (
   ...
   'lang' => 'pl',
   ...
);

but is there any way to do that without editing the query code?

Thanks!
