Right now, that is NOT possible to hide review box on non-review products.
The workaround is
Using Oberlo Integration Function (if you're in ESSENTIAL or PREMIUM plan) to quickly import reviews for ALL products just click 1 button without the need of filling product URL.
OR you can write the manually reviews for these non-reviews products in case you are in Starter Plan without Oberlo integration feature, OR using our Ali Orders app as an alternative solution.
