Unable to uncheck 'Allow requestors to approve their own changes' under Completion options

I was not able to find the switch to be able to uncheck the "Allow requestors to approve their own changes".
There is no switch for update policy.

$requiredReviewer = az repos policy required-reviewer create `
--blocking true `
--branch "main" `
--branch-match-type "exact" `
--enabled true `
--repository-id $($repositoryid) `
--required-reviewer-ids $reviewerGroupId `
--org $adoOrg `
--project $adoProject `
--message $reviewerMessage
