Does Turnstil inject inline javascript?

Is “ts-request-embed-key” a Turnstil request? I am trying to figure out where this inline javascript injection comes.

fetch(window.location.href, {
method: “GET”,
headers: {
“ts-request-embed-key”: “d77f9923-5065-484f-936a-10f0cc4b70ad:f90e18c42cdc879c67cc63bb15a9844d259907e07ee3223e2341d8631224fc8f”

Cloudflare support confirmed that it is. However when I asked them how to turn it off, they have not been able to provide an answer… It seems impossible to remove and is breaking AMP validation for some of my pages.
