Not that I am aware of. Outside of AEM, you only have the Assets API which will trigger a single operation at a time (https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/assets/admin/mac...). If you don't want to trigger the bulk update from within AEM, you could still add a servlet as a wrapper, and expose a URL which internally triggers one of the methods you mentioned to perform the bulk update (ACS Commons, etc.).
