Is there a way to find out with Tools like iw if a WiFi-Device will work with a 5GHZ WPA2-EAP WiFi?

Here is the output for my specific device (but the questions targets to find a general answer)

WPA2 and EAP are typically not implemented by the device in hardware, but in software. On Linux, this wpa_supplicant is the program used for this, and it works with pretty much all WiFi devices.
