Rand sort on searchCriteria getItems

Is it possible to have a random sort when searching with repositories? Checked dev docs and unsure. Not found much elsewhere.

https://devdocs.magento.com/guides/v2.3/extension-dev-guide/searching-with-repositories.html#sorting

use MagentoFrameworkApiFilterBuilder;
use MagentoFrameworkApiSearchCriteriaBuilder;
use MagentoFrameworkApiSortOrder;
use MagentoFrameworkApiSortOrderFactory;

$this->searchCriteriaBuilder->addFilter(MessageInterface::STATUS, [Data::ENABLED], 'eq');
$randomSort = $this->sortOrderFactory
    ->create()
    ->setField(MessageInterface::SORT)
    ->setDirection(SortOrder::SORT_ASC); // random sort here
$this->searchCriteriaBuilder->setSortOrders([$randomSort]);
$searchCriteria = $this->searchCriteriaBuilder->create();
return $this->messageRepositoryInterface->getList($searchCriteria)->getItems();
