Unfortunately, system76 developers added exactly that functionality to their firmware: https://github.com/system76/qmk_firmware/commit/a1ab70c3a28a...

So it is possible to reboot into the firmware update mode just by sending some bytes to the raw HID interface. Apparently they did not think about the security aspect of this feature.

Would you mind creating a GitHub issue to track this on? We may decide to change the behavior before production

EDIT: I have created an issue here: https://github.com/system76/launch/issues/17

We do not intend for the production firmware to include any software reset to bootloader functionality. It will require a physical keypress (Fn+ESC)
