Yes, but that doesn't work for having one iPad shared by family. That's about writing software to be used for shared iPads. iPads can be shared in a business or school setting and going through the administrative steps to implement that. https://support.apple.com/guide/deployment/shared-ipad-overview-dep9a34c2ba2/web https://support.apple.com/guide/deployment/shared-ipad-overv... talks about how to do it using a Mobile Device Management (MDM) server.
