 | -DeviceNamingMode | string | Device Naming expander | Controls how device naming is handled when unattend content is copied to USB media or injected into the FFU. Accepted values are Legacy, None, Prompt, Template, Prefixes, and SerialComputerNames. The UI shows None, Prompt, Template, Prefixes, and SerialComputerNames. When device naming is left untouched in the UI, the generated config does not write DeviceNamingMode, which preserves the script default of Legacy. Prompt rewrites the staged deployment unattend to the existing manual prompt placeholder and requires -CopyUnattend. Prefixes writes prefixes.txt and requires -CopyUnattend. SerialComputerNames writes SerialComputerNames.csv and requires -CopyUnattend. |
