VLA option not available in Unattend.xml creator

This occurs when Windows is installed without a volume license.

If you choose “I don’t have a product key” during the Windows installation, Windows defaults to Retail licensing. When DIA is launched it converts the license to OEM so customers may use the Windows 10/11 Pro the PC is entitled for.

To make the VLA /MAK option available, activate Windows using the either the MAK or KMS key & then relaunch DIA.
