  `MinimalReferrers` | Removes all cross-origin referrers and strips same-origin referrers down to the origin. Has lower precedence than `NoCrossOriginReferrers`.
  `NoCrossOriginReferrers` | Removes all cross-origin referrers. Has lower precedence than `NoReferrers`.
  `NoReferrers` | Removes all referrers.
+  `ReducedSystemInfo` | Reduces the amount of system information obatainable through headers and javascript, also causes hardwareConcurrency to respond with two cores.
+  `RemoveClientHints` | Removes client hints (information sent to servers about your system, similar to a user agent).
  `SetIpv6ProbeFalse` | Forces the result of the browser's IPv6 probing (i.e. IPv6 connectivity test) to be unsuccessful. This causes IPv4 addresses to be prioritized over IPv6 addresses. Without this flag, the probing result is set to be successful, which causes IPv6 to be used over IPv4 when possible.
