Variables are only exported when set, so you can temporarily unset the
option and set the variable in a shell function to get this effect.
You might need to make `noexport' more sophisticated.

% setopt allexport
% foo=bar 
% printenv foo
bar
% unset foo
% noexport() { setopt localoptions; unsetopt allexport; $1=$2; }
% noexport foo bar
% printenv foo
% print $foo
bar
