Could you update your post with the following notes.

Framework is working on an official update process for bare mainboards without battery.

As a note, you should do the following process to update your mainboard to properly update the PD controllers if following your hack. As when they are updated, they will power off the main board unexpectedly. So you need to do a 2 step update.

Background: The full update steps are:

1. BIOS
2. EC
3. Right side PD controller.
4. Left side PD controller
5. Reboot

To make sure both PD controllers are updated correctly:

1. Plug the power source to the left side of your mainboard.
2. Run bios update with your changes.
3. system will reset when left side PD controller starts updating and system will power off.
4. Plug the power source to the right side of the mainboard.
5. Run the bios update a second time. It will skip the update on the right side PD controller as it is already updated. And update the left side PD controller successfully.
