Does it support emmc?

Don’t know, don’t have this HW. Check Armbian forums for support.

Yes. You can easily install the system on eMMC. Start the system from the SD card and use armbian-config (the corresponding item for installing the system on eMMC). By the way, after installing Armbian on eMMC, you will be able to run any system from a USB drive. For example Libreelec or another version of Armbian (on eMMC Ubuntu\Debian on USB flash drives Debian\Ubuntu of another version).
