The latest version of Google Chrome Canary has a new feature to disable FLoC -- Federated Learning of Cohorts -- in Google's Chrome web browser.
One option that Chrome users had to opt-out of Floc was to disable third-party cookies. Now, with Chrome Canary build 93.0.4528.0, comes a setting to control FLoC directly.

The setting is not yet visible by default, but users may enable it in Chrome by making a change on the browser's experimental features page:
  1. Load chrome://flags/#privacy-sandbox-settings-2 in the address bar of the web browser.
  2. Set the flag to Enabled.
  3. Restart Google Chrome.
The flag is available for in all versions of Chrome, and has the following description:
Enables the second set of privacy sandbox settings. Requires #privacy-sandbox-settings to also be enabled
When set to enabled, it unlocks the FLoC toggle that gives users control over the feature.
Note: Google is running experiments in select regions currently. Privacy sandbox trials and FLoC may be disabled in the browser depending on the region and automated participation in the experiment.

To manage FLoC, do the following:
  1. Load chrome://settings/privacySandbox in the address bar of the browser.
  2. If turned on, disable FLoC on the page to turn off FLoC.
  3. You may also turn of Privacy Sandbox trials there, if turned on.
