Is this during \transformfont or during \installfont? From which parameters
you had to change, I would suspect it is the latter.

I assume you mean \setscalednotglyph.

You could achieve that by redefining \mtxtomtx_setscaledrawglyph, but it is
not straightforward and anyway I don't think that is your problem. The
problem should be that all the information in these commands get stored in
memory when TeX is building the glyph base, and there is a simple way of
telling fontinst to not do that. Just giving the command

\offcommand\setscalednotglyph

e.g. somewhere before \installfont should do the trick.
