It is RK3288, so an Armbian Rockchip kernel might do something, but I have no clue about DeviceTree and/or bootloader. Alpine is quite different from Armbian/Debian but maybe with that bootloader+kernel+DTB and Armbian rootfs it might do something, but make sure you have seril debug cable. In general might need to find solder points on motherboard/PCB or some specific resistor value on OTG ID pin.
