Hello Victor, thank you reaching out.
Indeed we have that feature, you can enable it at this link if you're using our paid plan in Shopify.

I'm using Judge.me Shopify App
How to enable thumbs(upvote/downvote) buttons for individual reviews?
I've seen example of Judge.me app having that feature.
But i couldn't find any documentation on this topic.
Do you have setting available for Review Widgets?
