OK. finally, I see your picture and why you said ENV;

For a hack:
With the root creds in effect, /root/.nsmbrc is consulted
and /etc/nsmb.conf is always consulted (as written in that file).
Write the password in either of it, mount, and wipe it out.

Other than that, I've no idea.
You'd need to wipe out the environment vars if you use it too.
