Ignore synthetic browser test from Web Traffic analytics

I’m using a synthetic browser test to monitor page’s performance which periodically loads a page (html) and other resources (JS, CSS etc.,) These metrics affect the Web Traffic analytics in cloudflare (like Total Requests, Cached and Uncached requests).

Is there a way to filter/exclude the automated synthetic browser tests data from showing up in cloudflare analytics? These automated test have a special request header to identify them.

Paid Plans let you filter results in the dashboard. But the filters are somewhat limited.

Here’s the documentation that covers most of Analytics:
https://developers.cloudflare.com/analytics/graphql-api/sampling

So, there is nothing similar for the free plan?
I’m okay even if I had to exclude an entire URL/path.

The Web Analytics pages for Web Vitals allows to filter by path. But such filtering options are not present in analytics tab
