    The instructions were tested on a Lenovo X1 Carbon 5th Gen (X1C5) on Arch Linux but should be applicable to other Lenovo models and Linux distributions.
BACKUP YOUR DATA! I created a bootable Ubuntu Image like this:
$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.
then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:
$ sudo sh -c 'cat /dev/nvme0n1 | pv --size 477G > /mnt/<external-harddrive>/something.img'
This took about an hour and trust me, if something fails you would be grateful having spend this hour instead of loosing your data.
Now we are ready to start.


Install nvme-cli, they have instructions for all major distros and compiling it from source is also rather easy.
Download the firmware update, in my case it was this one: https://download.lenovo.com/pccbbs/mobiles/fwnv25.zip
Unzip it.
Check you current firmware version:

$ sudo nvme id-ctrl /dev/nvme0 | grep fr
fr        : 1.9.<something>
frmw      : 0x2

Download the extracted update to your nvme drive:

$ sudo nvme fw-download /dev/nvme0 --fw=/path/to/update.img
# in my case the update file was called NVME_End2End_Lenovo_512_dvt_OPAL_Encrypt_and_Signature.bin

Commit the update

$ sudo nvme fw-commit /dev/nvme0 --slot=0 --action=2
if this fails, try action=1, which succeeded on my drive (could take some seconds before the command returns).

Reboot
Check if the firmware upgrade was done:

 sudo nvme id-ctrl /dev/nvme0 | grep fr
fr        : 2.7.8341
frmw      : 0x2

I got a massive speed-up from this update, previously my boot-time took about 15-20 seconds, now I'm ready in 5s or something:
