Different source for Mathjax

Howday, we've got a situation where we want to run our shiny application offline.

Problem is that mathjax assumes access to:
https://mathjax.rstudio.com/2.7.2/MathJax.js?config=TeX-AMS-MML_HTMLorMML

Is there any way to change the source of this so we can make it locally accessible?

Cheers,
Roy
