Question How can I get HMD model at runtime?

Hello, I am using OpenVR/SteamVR in a software that uses VR. This software integrates some eye-tracking features that can be used with HMDs like Vive Pro Eye. How can I know which HMD is using the user in order to activate/deactivate these eye-tracking features if that HMD doesn't have an eye-tracing technology?

Thank you
