Hi @Harshdeep Thakur ,
Currently with Microsoft Graph, we don't have property to differentiate if booking business is Available to people in your organization and Available to anyone.
If bookingbusiness-publish is used it will set publicly accessible url.
A similar post Restrict Bookings Business appointments to organisation only via API.
Hope this helps.
