AR Foundation - non compatible devices support

Hi, whats the support mechanics for devices that don't fall with compatibility with AR Foundation ( AR-Kit and AR-Core) ?
Can I still deploy to those devices (on the stores) and is there API's for me to implement non AR alternative?
Or is this a no go for android/iOS?

Thanks.

a little background the app I'm working is heavily non AR, but the design contains elements that might be AR enabled, but the user device could be given a non-AR alternative to support those if I can A-know if AR is not supportive, and B- built and onto the stores with the same app.

 

Hi - did you find / make a solution for this?

UPDATE: appartently the documentation covers this right at the start, in https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@2.0/manual/index.html#basic-setup under Checking for Device Support
