Ah, the late timing of the prepare_field filter seems to make this possible via the $field[‘value’] key

function preselect_an_option( $field ) {
   
    if (isset($_GET['book_author'])){ // or however you get the value dynamically
        $field['value'] = $_GET['book_author']; // this is where it gets selected!
    }
    return $field;
         
}
add_filter('acf/prepare_field/name=book_author', 'preselect_an_option');
