Yes. HTC Vive XR Elite has its own browser, and that is all it takes: Hrava runs the game on your Mac and streams the picture to the headset over Wi-Fi. Nothing needs to be installed on HTC Vive XR Elite.
Vive XR Elite can be worn as glasses with the battery cradle removed - handy when you want to see your keyboard. Built-in diopter adjustment means you can play without your glasses. Its Chromium browser decodes H.264 in hardware; keep the Mac and headset on the same 5 GHz network for stability.

Install Hrava, turn on VR streaming - and see for yourself in minutes.
