For work and school profiles, the toolbar will show a "Work" or "School" label by default next to the toolbar avatar. The label will only be shown if the signed in account is managed. Setting this policy to hide_expanded_enterprise_toolbar_badge (value 1) will hide the enterprise badge for a managed profile in the toolbar. Leaving this policy unset or setting it to show_expanded_enterprise_toolbar_badge (value 0) will show the enterprise badge. The label is customizable via the EnterpriseCustomLabel policy.
