I need to typeset a glissando from e-flat to e and I'd like it to look as if
it'd go upward, right now the line is straight and not actually visible

I suppose the property to edit is normalized-endpoints but changing it
didn't seem to have any effect.
You need :
\override Glissando #'left-bound-info #'Y
and
\override Glissando #'right-bound-info #'Y
To use the precomputed values with a bit of an offset, you can override
left-bound-info and right-bound-info without the Y, extract the Y info, play
around with it to suit your fancy, and return a new alist containing the
tweaked Y values.
