Rock 4c+ emmc image update

Hi there, this is my first post here

I’ve had my Rock 4c+ for almost a couple of years at the moment I use it for LibreELEC when I want to use a new image I take out the emmc flash module, install it in a usb adaptor and flash a new image then put it back in the Rock 4c+ then boot it, but what I would like to know, is there a way to flash a new image to the emmc with it installed in the Rock 4c+ without having to take it apart and putting the emmc into my usb adaptor?

Thank you very much for the help

maybe this guide can help you
