Disable loading of Google font

Hi,

I’m busy optimizing one of my customer webshops which runs the CO2ok plugin. I see in the source the plugin is loading https://fonts.googleapis.com/css?family=Roboto%3A400%2C500%2C700&ver=5.7.2&display=swap

How can I disable this? It’s causing pagespeed to report “Eliminate render-blocking resources”

Cheers,
Jaap
