Minix U9-H USB power while in standby

Hi, does anyone know if its possible to have the USB ports powerd off when the U9-H shuts down? currently I have 2 SSD’s attached and when I shut down the U9-H the SSD’s still remain powered on, I would rather not have them powered on 24/7


This would require modification to the bootloader which is not something that we do for TV boxes because each model of device generally needs it’s own unique bootloader.
