doesn't nanoBSD run in ro-mode per default, ie it should be somewhat tamper
proof as is, even installed on disk.

If running from optical drive is important, I would have a closer look on
how pcbsd/trueos sets up their install-discs ( or at least used to, haven't
tried one in a while ) where they basically load the entire file system
into ram from a compressed image on the optical disc.
