bundle.js and bundle.css

Hi,

the theme use two files loading from your server
https://www.idxhome.com/service/resources/dist/wordpress/bundle.js and
https://www.idxhome.com/service/resources/dist/wordpress/bundle.css

I want to load both files from my local server (to make my PageSpeed Insights better)
But I cannot find where to modify these paths?

Any help is much appreciate

Thanks
