Are you able to boot from USB on the Radxa Pi Zero?

Everything I have seen says that you can boot over emmc or micro-sd but the only way to “boot” over usb is by pressing the button on the bottom, and from what I understand that just makes the emmc a usb storage device so you can repair. Is there any way to boot over the USB-C without the use of a button? To just power it and have it read the USB automatically?
