Yes but they don't have my laptop in the device list: no Carbon X1 Gen 6 (only Gen 9)
I have that laptop and I've gotten quite a few updates through fwupd.
Honestly, given how annoying the alternatives are, I would say just buy a USB drive and put the bios file on there. You can get very good ones for under $20 and almost free ones if you don't mind having an old tiny one.
This is the real answer. In this day and age where a 16gb USB stick can be had for literally $5usd on Amazon, it would be silly not to have a few kicking around. I donβt think any Linux distro live environment media requires more than 16gb, and itβs more than enough for updating a bios. I even used one to update the infotainment system in my vehicle last week. Kind of a necessary tool.
Even if you need one immediately and can't wait on Amazon, it's back to school season. They are plentiful everywhere. Target, Walmart, Kroger, Staples, Office Depot, etc. etc. etc.
I just did this for the motherboard on my desktop PC (thanks Intel and your CPU update!) and it requires a clean boot device of some kind to boot into UEFI. It has nothing to do with the OS of the device.
In my case, yeah, I did it from a thumb drive, but I could see making a boot CD that has the bios files on it as well.
OTOH if you have the capability of burning and booting a boot CD it's probably way easier to just use a thumb drive.
One thing I'll note, on my motherboard, only using the keyboard to navigate the UEFI menu failed to update. :( I had to connect a physical mouse to run the menus.
Copy bios image to uefi partition and try to open it when in bios, if there is flasher in it.
Without usb?
Dual boot into windows and use Lenovoβs utilities.
I don't have windows
