           You can enforce virtual backgrounds, requiring users to use a virtual background to enable their video. This applies to internal, external, or both types of meetings. You can choose whether all administrator-uploaded backgrounds or only selected ones are available for the users. Enforced virtual background settings override the options configured in the Allow virtual backgrounds section.
