Google Lighthouse report - can we manually set cache policy (TTL and expires headers)?

I’m doing contract work for a client; which started by running a Lighthouse report against his website.

Among the issues it reported were a number of static files which are being served with a non-optimized cache policy. I can’t find a definitive answer on whether or not I’m able to manually set those values on WebFlow. Could someone tell me if this is possible (and where I can find those settings), or if it’s not possible?

This is the specific section I’m concerned with at the moment.

You have Zero control over assets being served via Webflow’s CDN other than the actual file. If you need more control then you would need to host them yourself where you do.

Thanks @webdev, I was afraid of that. Appreciate your time.
