Finally new Dell XPS 13 2-in-1 9365 NVM firmware. Went from NVM09 to NVM23.

External GPUs supported: No is still present, but that never stopped it from working with eGPUs.

But since Dell can be a little incompetent, it no longer shows in website.

This carries digital signature from Dell Inc.

If anybody ever needs to downgrade the Dell NVM firmware, you use 7-zip on the file, and from elevated CMD, you do:

FwUpdateCmd.exe Up1 /f firmware_file.bin

With an active TBT3 controller. Need to plug something in first.

Other option is to do it manually in Linux using dd command to /sys/bus/thunderbolt/devices/X.X/nvm-non-activeX/nvmem and then echo 1 into the nvm_authenticate file in previous directory.

The only way I know of to back up firmware from the vendors who do not provide images is with Linux and dd from the nvmem in nvm-active. Windows is definitely capable of doing it with WMI, but I do not know of an application that actually does it.

Make sure you know what you are doing. De-bricking could be impossible for most people (if you flash something incompatible). I have done it with TBT3 AIC with a ROM programmer and SOIC test clip. But I am extremely persistent and stubborn.

Thank you @karatekid430 for sharing the NVM firmware and downgrade how-to. Backing up the TBT firmware from an enclosure is highly desirable. One example is the case of Sonnet 350 and 550. One has a 15W PD and the other has 87W PD. You can install a beefier PSU but that power delivery figure doesn't change due to the enclosure firmware.

We'd greatly appreciate a step-by-step guide in the Linux setup sub-forum if you have the time to document the process.

I still plan to do a full guide as requested, but it is so busy.

If anybody is interested, Dell did it again, this time with their BIOS for Dell 9365.

Either they are not very organised, or they are releasing dodgy updates and then revoking them.

Either way, the files I added to the OneDrive directory might be of interest.

Right now, I can only find BIOS 1.1.0 - despite 1.2.1 having been there in the past. Some of the files I added are still available - I couldn't be bothered sorting them. All carry digital signatures from Dell Inc.

If installing, bear in mind that if they revoked it, it might be unstable. Although I had 1.2.1 installed previously and it did not destroy or brick my computer.

Now for shameless self promotion time. I asked this question regarding Thunderbolt on Intel forums and was hoping people might be interested:  https://communities.intel.com/thread/122304

Edit: The reason for withdrawal I have discovered here:  https://www.dell.com/community/XPS/XPS-13-9365-BIOS-v1-2-1-installed-but-gone-1-1-0-available/m-p/5776058

Spectre patch instability; withdrawn after notice by Intel.

Many thanks (Edit 2: \sarcasm) to Dell for notifying users running the BIOS, and providing explanation for its disappearance. Still, if you really want the file, it is here. They should still allow people to download withdrawn updates after a banner notifying them of the risk.

Since Dell completely pooped the bed again and wrecked most of the driver downloads, here is the 1.4.0 BIOS for Dell 9370, added to the same Onedrive link as before:  https://1drv.ms/u/s!AuN0OlwU3-gMg-VzUFsKIZaEbJ4Duw

Also I threw in the NVM28 Thunderbolt firmware (not the most recent) because it disappeared. NVM33 is still available for download from Dell. NVM23 comes loaded from the factory and was never provided as a download - the only way to get it is to extract it from the controller in Linux.

Turns out not all files were being shared when added to the directory. Hopefully this will fix it.

EDIT:
Dell re-released 1.4 - updated and it works fine, so back to recommending the NEW version of 1.4.0!  So just make sure you check your power limits and that you can draw up to 27W
