Both are capable of booting from the NVMe drive perfectly. This has been tested on XPS 9343 as well as a Dell Optiplex 790. Worst case scenario you can flash your dump back if it doesn't work. Works on other systems, but will require a different method on systems with updated BootGuard PEI. This Shouldn't, but may change or break existing features.

With some basic knowledge of how to remove the bottom panel, and a Google search on using a SOIC clip, you should be able to manage this modification. Not sure if anyone has done this, but if you know how to without disassembly of your system, you can use that method instead. Short of exploiting the write protect on this system, you'll neeed to disassemble and flash with a programmer.

There are very likely some small issues with this method, or at least missing features one may expect when compared to systems shipped with full NVME support. This will add basic support for NVME drives on the Dell XPS 13, model 9343, and likely other laptops sporting unpatched Intel BootGuard. All of this is at your own risk and you are responsible if your system dies, catches fire, or your cat stages a coup.

Read EVERYTHING before attempting, especially if you haven't flashed or modified firmware before. You must modify your original BIOS, as your Windows key and hardware serial numbers are baked into that firmware. It will either not work and brick the device, OR will deactivate your Windows install and you will not be able to reactivate it without flashing back or buying a product key. IMPORTANT: Do not flash the example file to your own board, ESPECIALLY if you have not made multiple backups and confirmed that your backup is a perfect dump.
