FirstPartySetsEnabled

This policy is provided as a way to opt-out of the First-Party Sets feature (which was later renamed Related Website Sets feature). When this policy is unset or set to Enabled, the First-Party Sets feature is enabled. When this policy is set to Disabled, the First-Party Sets feature is disabled. It controls whether Chrome supports First-Party Sets related integrations. This is the equivalent of the RelatedWebsiteSetsEnabled policy. Either policy may be used with the same effect on the browser's behavior. Both these policies are deprecated following Google Chrome version 144.
