You can't; NFS has some concept of (a few) filesystem
attributes. These really are different filesystems underneath,
with different attributes. What you can do instead is have the
mounts occur automatically. Look at amd(8); I think the
example in the Handbook is a little different from your
configuration, but I'm pretty sure that somewhere back in the
mists of time I did something similar to what you want.

[Caveat: I don't know NFSv4 that well. But I'm pretty sure
that doesn't change the answer.]
