Multiple Post Types for field type: select_advanced

I want to allow multiple post types to select_advanced field. I have a post type named "plot", but I also want to add another post type in the autosuggest.

See commented below.

array(
                    'name'        => esc_html__( 'Plot', self::$namespace ),
                    'id'          => self::$pin . '_plot_id',
                    'type'        => 'post',
                    'label_description' => esc_html__( 'Start typing', self::$namespace ),
                    'post_type'   => 'plot',  <-----I WANT TO ALLOW MULTIPLE POST TYPES HERE---->
                    'field_type'  => 'select_advanced',                   
                    'query_args'  => array(
                        'post_status'    => 'publish',
                        'posts_per_page' => -1,
                    )
                )

I couldn't find it in the docs. Is this possible?

Or can I achieve this using another field type?
