HP Desktop M01 PCIe transfer mode is x2 (should be x4)

[XStoneX]

 I've build the 1st gaming PC out of a HP Desktop M01-F0211ng  and upgraded this little peace of hardware to the absolute maximum:

- 400W NT (HP original)
- Ryzen R7 3700X
- 2x16GB DDR4-3200 CL16
- 2GB Samsung 970 Evo Plus (nVME, PCIe 3.0 x4)
- Zotac GeForce RTX 4070 Wind Force OC 12GB GDDR6X (PCIe 4.0 x16)
- Noctua NH-L9x65 CPU Cooler 
- Noctua NF-A8 FLX side fan
- Noctua NF-A9 PWM back fan

The system is running quite fast, but sadly the BIOS seems to cut the PCIe transfer mode of the nVME SSD to PCIe 3.0 x2. This info is shown with the Samsung Magician 8.0 software and CPU-Z. 

HP itself declares the board with support for nVME SSDs up to PCIe 3.0 x4. Why is the mode cutted to x2? Can you please change this into x4? Should be possible to do this by a BIOS update. 

Another user had the same issue: 

HP Desktop M01-F1024 PCIe transfer mode is 2x vs 4x - HP Support Community - 7942383

Thanks for your efforts and support!
