When I wanted to make my math text in a LaTeX beamer presentation upright, I
added the following to my beamer style file:
%%Attempt to get upright math symbols
\AtBeginDocument{

I don't know if that helps here. Perhaps you would add this to
rcParams['latex.preamble'], which was always advertised as being experimental.
(You may need to preface it with \makeatletter, and end with \makeatother.)
