I don't know of a way.

However, note that you can send the Ctrl-U over the serial console too,
so any scripts you use to automated the boot can do it that way.

Wow, it's really surprising to me that that works. Thanks!

Unfortunately no, there's nothing there AFAICS about permanently
altering the bootloader or settings to prefer USB booting without
hitting ctrl-U.

From what I've found making this change would likely mean opening the
chromebook and shorting pads or some other trick to enable overwriting
the bootloader on the device. At least, that's what is partially
documented on this page about installing Arch on an earlier Samsung
chromebook model.
