Serve static assets with an efficient cache policy - woff2 CSS - pagespeed google

[jbeltran73]

Hello, I've almost got the eight 100's in the pagespeed. 

I send you screenshot. 

The only modification that I can't achieve is to load woff2 files cache as 30days. 

Where can I modify this? The only way I see it's creating a Child theme and edit the CSS there? 

Any solutions without creating a child?

Thank you

Pd: here is the error

Hubspot automatically sets a cache time on served assets, so it's not possible to change the cache policy for Hubspot files I'm afraid.
