not quite sure what your asking, but this can display device info and more.. 

https://github.com/root3nl/SupportApp

depends what info you want to display.. an alternative would be

 https://github.com/bartreardon/swiftDialog

There's also this, from Bill Smith @ Jamf (aka @talkingmoose)

https://www.jamf.com/blog/build-a-computer-information-script-for-your-help-desk/

It uses Applescript, so doesn't rely on a 3rd party app being deployed. An oldie but a goodie.

I'm using Bill Smiths solution, with some modifications. Some stuff we didn't need, other stuff we wanted.  It works quite well, but for that far away point in where I have more cycles to waste on side projects I have it on my to do list to switch to Swift Dialogs so we can get a consistent user experience.
