AR Foundation - Make iOS Arcitecture Optional

I am using AR Foundation for doing builds for Android and iOS. My App has AR as an optional feature, and I only enable it if a device is AR supported following this:
AR Foundation: Unsupported devices are passing enabled test. .
I want to know if there is way I can do Universal Architecture builds for iOS. Because if I do Arm64 only builds, it drops the support for my app on old devices like iPAD 3.

@sameel Have you found any answers to this question?

@Neo-Pangea No, we have changed the build setting to Arm64 only.

Is there even much usage of old devices such as iPad 3? I have a hunch that pretty much everyone is using new devices these days. If you have some statistics I’d be interested to take a look.
