You can install Windows on your Steam Deck, in this guide, it steps you through the process of installing Windows 10/11 to a microSD card. Thus allowing you to easily switch between SteamOS and Windows. Please see the Q&A Section of the guide for some of the most common questions that you may have.
Once Windows 11 has been installed and booted, the nreal air glasses will work for Air-Casting, just as they do in SteamOS. When you right-click on the Desktop and select Display Settings you’ll see the nreal glasses appear as a monitor. Instead of mirroring the display, you may prefer to extend the display and may want to set the nreal glasses to Make this my main display (checkbox). This will allow you to utilize the full 1920x1080p resolution while wearing the glasses.
