In *nix, almost anything is possible. You could either excise the
protected lines with e.g. Awk, then reinsert them after exit from Vim
to the wrapper script, or leave them for whatever user benefit exists,
then overwrite them on exit, to defeat edits.

The protection zone could be primitively defined by line numbers, by
recognisable intrinsic content, or by arbitrary added delimiters.

If it were necessary to enforce reciprocal protection, i.e. those with
permission to edit the primary protected text should not touch the other
text (even if only to avoid finger fumbles), then the two halves could
perhaps be kept as identically named files in two adjacent directories,
with differing group ownership and limited write permissions, merged
only for consumption, not for editing.

In that case, Vim could be invoked on both files, perhaps in two tabs,
with the correct one automatically being read-only, as enforced by the
*nix permissions of the files, and the *nix group membership of the users.
