Dell Precision 3551 - Quadro P620 VBIOS Missing/Corrupt - Known Manufacturing Defect?

Hello Dell Community,

I am posting about a known issue affecting the Dell Precision 3551 with NVIDIA Quadro P620 graphics that I believe is a manufacturing defect involving a missing or corrupt VBIOS.

SYSTEM DETAILS:
- Lapmargin: 0;">THE PROBLEM:
The Quadro P620 cannot be initialized by any NVIDIA driver version on Linux. The consistent error is:

NVRM: GPU 0000:01:00.0: RmInitAdapter failed! (0x24:0x72:1590)
NVRM: GPU 0000:01:00.0: rm_init_adapter failed, device minor number 0

The GPU UUID shows all question marks: GPU-????????-????-????-????-????????????

ACPI warning at boot:
\_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package]

WHAT I HAVE TRIED:
- NVIDIA drivers 535, 580 (latest supported for this GPU) - same error
- NVIDIA driver 590 explicitly rejects the card as legacy
- Kernels 5.15 through 6.8 - same error on all
- BIOS reflash to 1.41.0
- Multiple kernel boot parameters (pcie_aspm=off, intel_iommu=off, acpi_osi fixes)
- ACPI power calls via acpi_call module
- ZFS removal (was conflicting)
- PCI bridge unbind/rescan

VBIOS FLASH ATTEMPT:
I found Dell's critical VBIOS update: NVIDIA_P620_VBIOS_v1.0.0.1.exe (driver ID 1g3jx). When I attempted to run this from a Windows PE environment, the tool reported:

"No display adapters were found that are compatible with this update."

This matches reports from other Precision 3541/3551 users on this forum who found their replacement motherboards came WITHOUT a VBIOS installed on the P620 - described as a step missed on the production line.

The GPU IS visible on the PCI bus (lspci shows it correctly), but nothing can initialize it - not the NVIDIA proprietary driver, not the VBIOS flash tool.

REQUEST:
This appears to be a known manufacturing defect affecting multiple Precision 3541 and 3551 units. Can Dell:
1. Confirm this is a known issue
2. Provide a way to flash the VBIOS directly (the current tool cannot find the GPU to flash)
3. Consider a warranty repair/motherboard replacement given this is a manufacturing defect

I have a detailed NVIDIA bug report and full dmesg logs available if needed.

Thank you.
