For Rocketchat version 6.5.0 and later, I have read that workspace registration is required.
But after registering the workspace, the domain name of the rocketchat instance will be shown in rocketchat cloud. Is it possible to register workspace without the domain name? Or perhaps bypass this workspace registration so that I can continue to use rc?
Thanks!
In a word, no.
Have you read the docs?

But it has to be genuinely airgapped.
I think there is still a method somewhere to skip registration, but if it hasn’t been removed it will be soon.
But you will lose access to items like push notifications, apps etc.
Alternatively take the code, remove the bits you don’t like, and rebuild yourself. That’s open source!
