Well I allways use to write protect my Alladin advance installs using this method:

Now is this possible on Duox2's by cutting or removing one of the pins or traces?

CODE

Write cycles are inhibited by holding any one of OE# =
VIL, CE# = VIH or WE# = VIH. To initiate a write cycle,
CE# and WE# must be a logical zero while OE# is a
logical one.


From the data sheet.

That means tie #WE high to write protect the rom.
