Hi Greg Bontrager,
Thank you for reaching Microsoft Community.
Surface Pro X is compatible with Windows 11. We recommend you wait until your device has been offered the upgrade to Windows 11. You'll be notified through Windows Update that the upgrade is ready for your device. To check if Windows 11 is ready for your device, select Start > Settings > Update & Security > Windows Update > Check for updates.
The Windows 11 Installation Assistant is only available for x64-bit processors.
Kind regards,
