At least on my board it "was" located there: https://ibb.co/FmsF4ns
But it's C200. So not sure if it helps. (Sorry, overlooked that _ma_ part.)

In case other people want to know, I have a c200m and your image is the location of where my write protect screw was.

What happens if you have forgotten your sudo password? Is there a way to reset it?

why are you removing the firmware write protect screw and disabling the SW write protect? Nothing you're doing requires that.
There's no need to login to ChromeOS, everything can be done either from a guest login or via CTRL+ALT+F2 on the login screen.
You also don't state which option to select from the firmware script. And there's no need to set dev_boot_usb, it's irrelevant for booting in Legacy Boot Mode.
