Any utility function to work out if app is running of Vive Focus or normal Android Phone?

[tom_fv]

I'm trying to make an application that will load the appropriate scenes depending on the platform, we're trying to add the Vive Focus to be one of those platforms, but I can't find anything in the documentation that will enable me to check whether the android device is a Vive focus or not, anyone already solved this or has any ideas?
