You achieve this in two ways:

1. adding 'display_names_as'=>'slug' to the args

   $args = array('show_flags' => 0, 'show_names' => 0, 'hide_current' => false,'dropdown' => 1,'display_names_as'=>'slug'); pll_the_languages($args);

2. Polylang hook Just add this snippet in your function.php file:

   add_filter( 'pll_the_languages_args', function( $args ) { $args['display_names_as'] = 'slug'; return $args; } );
