add_fitler('acf/load/field/key=field_XXXXXX', 'my_dynamic_select_field', 20);
function my_dynamic_select_field($field) {
  $choices = array();
  args = array(
    'post_status'    => 'publish',
    'posts_per_page' => 6,
    'meta_key' => '_wp_page_template',
    'meta_value' => 'page_people3rd.php'
  );
  $query = new WP_Query($args);
  if (count($query->posts)) {
    foreach ($query->posts as $post) {
      $choices[$post->ID] = $post->post_title;
    }
  }
  $field['choices'] = $choices;
  return $field;
}

You could also yous a post object field or a relationship field and then use https://www.advancedcustomfields.com/resources/acf-fields-relationship-query/ or https://www.advancedcustomfields.com/resources/query-posts-custom-fields/ to alter the query done to populate the page.

function my_relationship_query( $args, $field, $post_id ) {
	
    // only show children of the current post being edited
    $args['meta_key'] = '_wp_page_template';
    $args['meta_value'] = 'page_people3rd.php';
	
	// return
    return $args;
    
}

// filter for every field
add_filter('acf/fields/relationship/query/key=field_XXXXXXX', 'my_relationship_query', 10, 3);
