Ok, the latest commit now allows you to rely on pdflatex only. Xelatex is
still the default, but you can change that using the rc parameters:

matplotlib.rcParams.update({
  "font.family": "serif",
  "pgf.texsystem": "pdflatex",
  "pgf.preamble": [r"\usepackage{siunitx}",
r"\usepackage{somefontpackage}"],
})

System fonts specified in the rc parameters will be ignored since pdflatex
cannot use them. Font metrics will be obtained from a pdflatex process. If
you save the figure as pdf, pdflatex will be used to compile the figure.

Hope this helps.
