BIOS from Precision 5530 suitable for XPS 9570?

Hi,

I just have bought an used XPS 9570. At the moment I' m working on installing Windows 11.

I noticed that from this XPS a second variant exists, the business Modell Precision 5530.

The device seems to be widely the same. (same motherboard?) The Precisions has of course CAD capability with the Quadro variants of the graphic card.

Now there is an older Bios 1.27 for the XPS and an older Thunderbolt firmware 4.46.143.004. The Precision 5530 has BIOS 1.37 and Thunderbolt Firmware 4.46.143.009. Both have solved many security problems.

Until 1.27 the BIOS file seems to be the same for the different Systems.

Now there is Linux Firmware-Updater offering the newer Precision 5530 Firmwares for the XPS 9570.

Is this a mistake from the updater? Or can the newer Firmwares of the Precision 5530 in fact be installed on the XPS 9570 without problems?

Would it be possible that somebody from Dell could answer this? I would also be pleased if there would be an "inofficial release" if somebody would say yes. I think the firmware was only not offered, because the Precision get longer support as the consumermodel XPS? But the new files have not to be programmed new for the XPS and are already existing. => I hope there would be an answer with yes. This would be very great if i could actualise the device and close the security problems.

Thanks!
