In short, loading the brn u-boot variant via serial console/ brnboot (open the device and access the serial header - or get inventive with short pipes to go through the vents of the closed device) and then flashing the NOR u-boot via tftpboot (run write-uboot-nor); loading/ flashing LEDE from there via tftpboot after rebooting into the NOR u-boot.
That's not available.
