Hi,
I have the issue on masonry grid. It’s certainly the same with any visual element using text.
Didn’t see any option to use custom font, even to choose whatever font. Even if I go in element / template customisation. Further, it may demand to load all alphabets, Roboto & Montserrat.
You can have a look on staging site below, home page.
