exports file options

I’m having the same problem with my modified exports file getting overwritten as in this old ideas post
https://community.wd.com/t/idea-ex4100-no-root-squash/242432

I need to use the no_root_squash to set up the EX4100 as extended storage for our Linux backup server.

Since there is no way to set the exports options in the web interface is there a defaults or setting file that persists that can be edited?

Thanks in Advance
