You are right that it is not possible: #+BIND is effective only when you
are exporting - basically, people wanted to change various setting on
export, and adding options for each and every one was too much, so
Carsten implemented BIND as a general mechanism for that. But it does
not apply to anything else; in particular, code block evaluation is
completely separate.
But you can use general emacs mechanisms to set it for a particular file:
that's what file local variables are all about:
(info "(emacs)Local Variables in Files")
