For Apple push notification, can I send without device token?

I just want to broadcast push notifications to all registered devices without having to keep track of all registered device token. Is this possible? I think it's not possible but I still can't find an official word on this. So I just want to make sure.

In APNs, assurance of accurate message routing—or token trust—is made possible through the device token

For more detail as mentioned in Apple documentation :

Apple Push Notification service transports and routes a notification from a given provider to a given device. A notification is a short message consisting of two major pieces of data: the device token and the payload. The device token is analogous to a phone number; it contains information that enables APNs to locate the device on which the client application is installed. APNs also uses it to authenticate the routing of a notification. The payload is a JSON-defined property list that specifies how the user of an application on a device is to be alerted.

To enable communication between a provider and a device, Apple Push Notification Service must expose certain entry points to them. But then to ensure security, it must also regulate access to these entry points. For this purpose, APNs requires two different levels of trust for providers, devices, and their communications. These are known as connection trust and token trust.

Connection trust establishes certainty that, on one side, the APNs connection is with an authorized provider with whom Apple has agreed to deliver notifications. At the device side of the connection, APNs must validate that the connection is with a legitimate device.

After APNs has established trust at the entry points, it must then ensure that it conveys notifications to legitimate end points only. To do this, it must validate the routing of messages traveling through the transport; only the device that is the intended target of a notification should receive it.

In APNs, assurance of accurate message routing—or token trust—is made possible through the device token. A device token is an opaque identifier of a device that APNs gives to the device when it first connects with it. The device shares the device token with its provider. Thereafter, this token accompanies each notification from the provider. It is the basis for establishing trust that the routing of a particular notification is legitimate.

You can not send PUSH notification without enabling on appId and with out device token.
