My serial number is SLarBXGZ1H240103175.  
BIOS shows NVME in boot options, but Windows 11 installer and CHUWI recovery USB cannot detect the internal NVMe disk.  
Is DNB19C\_003\_CW\_EC1.02\_231206 the correct BIOS/EC update for this unit?  
Please provide the correct OS image, BIOS/EC firmware, and storage driver if needed.
