If all you are doing is replacing includesvg with simplesvg, then you
might try this:

#+BEGIN_SRC emacs-lisp
(let ((org-export-filter-link-functions  '((lambda (txt _ _)
					     (replace-regexp-in-string "includesvg" "simplesvg" txt)))))
  (org-latex-export-as-latex))
#+END_SRC

If you are doing more than that (it looks like you are adding options?)
then one alternative option is just put a copy of your modified function
in your init file after you load org, and then it will shadow the
ox-latex function and you might not have to change anything when you
update as long as no incompatible changes are in the update. I know,
that is hacky, but it works in cases like this.
