I asked copilot and it gave me this response, try it !, if it works then you can just apply the registry key via a step in the task sequence just before it normally shows up
Open Registry Editor:
Press Win + R, type regedit, and press Enter.
Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE
Create a new DWORD (32-bit) Value:
Name it SkipMachineOOBE.
Set its value to 1.
Create another DWORD (32-bit) Value:
Name it SkipUserOOBE.
Set its value to 1.
These changes should bypass the "Just a moment" screen during the OSD process.
