Nitrowall: Boot from USB

NitroWall

Hi,

I want to install a fresh OPNsense on the Nitrowall. I Have a USB stick which boots fine on other PCs. When I plug the USB stick into the Nitrowall it boots the default OPNsense from the internal SSD. How can I configure the Nitrowall to boot from the USB stick?

Hitting ESC during startup gives this…
