Enable the app only for iPad and iPhones with high RAM memory

I've finished a educational game, mainly for iPad, and the problem is that it automatically exits in older phones. It contains many videos, images and sound, so for example in iPhone SE it can't be run properly. I don't know where can I exclude certain iPhone models to prevent users to try it and give them a bad impression. I've been lookin in App Store Connect and I can't find that option.
