How to purchase Foxconn or Fujitsu tested 5G O-RU radio for Nvidia Aerial SDK platform?

How do we purchase the Foxconn or Fujitsu 5G O-RU radios that are tested and approved for use by the Nvidia Aerial SDK platform?
We want to purchase only 1 or 2 low power O-RU indoor radio units with a shipping time of up to 90 days for our indoor 5G NTN satellite communications research lab.
Nvidia, Foxconn, Fujitsu, and other radio vendors do not appear to have in-stock 5G O-RU radio inventory or a clear path to purchase 1 or 2 O-RU radios that are tested to work with the O-DU of the Nvidia Aerial SDK 5G radio development platform.
