Currently, Ali Reviews has not yet supported this setting.
However, you can do that with a third-party app, Transcy app, that are officially integrated with Ali Reviews.
After installing Transcy, make sure that you turned on "Third-party Apps" function, and you will see a magic thing in your store. More details can be found here
Please be advised that "Third-party Apps" function will translate based on your target language, NOT default language. For making it clear, if your store default language is English as an example, your reviews cannot be translated into English again.
More than that, Transcy can help you to:
Translate your store page into multiple languages with 241 languages over the world.
Choose any specific section/page on your storefront that you want to translate, and edit the translation by elements easily and quickly.
Auto translate content every time there's any change in your store's content.
Upload and display any pre-selected media (images/banners) for each target location/language.
For more detail how Transcy can bring about benefits can be found here.
