How to flash Up Board Squared?

So far I've built an image with Yocto, creating the hddimg that I flash to a USB and then press install.

However, I want to install this to 20 Up boards, and this process is quite tedious. Is there a way to flash the eMMC directly? Some CLI tool so I can connect the Up board to a computer and then flash the eMMC?
