Unfortunately, it’s not possible to restrict the tenant’s access for a specific time. You can submit Product Feedback on our Community page to add more weight and visibility to the request; here is our link: Feedback - Auth0 Community. You can read our FAQ regarding submitting a feature request here: How to Submit Product Feedback or Feature Requests.
