The Heads update was tested on the Lenovo ThinkPad x230.
You need to build and flash Heads ROM from the 3mdeb fork. Currently, you need to pass custom metadata URL:

You will find there Heads ROMs for ThinkPad x230.
ThinkPad x230 is now the only laptop that has Heads ROM in the custom LVFS
storage. Nevertheless, qubes-fwupd has already implemented a device flag, that
will allow updates for other hardware.
At first run the qubes-fwupd Heads update.
sudo qubes-fwupdmgr update-heads --device=x230 --url=https://fwupd.org/downloads/firmware-3c81bfdc9db5c8a42c09d38091944bc1a05b27b0.xml.gz
Press Y to reboot the device.
In the main menu, choose options and then go to Flash/Update the BIOS
