No, there is no option to make zoom from the gallery but we have the option in our Theme Options -> General ( https://prnt.sc/Y1BsYw7buS8i )
After you activate it customers will be able to zoom your side so that images will be ready to scaleIn as well.
Hope activating that option will be ok for your reasons.
P.S. for now it is active on your staging2… (clear cache and see changes from mobile device)
