Looks like I was close. I needed to set the ‘default_value’ attribute:

function acf_load_shorturl_field( $field ) {

    // Get shorturl value
    $field['default_value'] = get_shorturl();

    // return the field
    return $field;

}
add_filter('acf/load_field/name=shorturl', 'acf_load_shorturl_field');
