Can a deleted 1TR container be recreated without wiping the hard drive?

[rubenrp]

I’m working with an M1 MacBook Air where the 1TR container has been accidentally deleted. As a result, Big Sur updates will no longer install, and the default Recovery system is gone. I have two questions that I’m hoping someone can help me with:
- Will the Configurator 2 DFU Revive option both recreate the 1TR container and reinstall the recovery system? Or does it need for the 1TR container to exist before it can do anything?
- If the latter is the case, is there a way (from e.g. Terminal) to recreate the 1TR container correctly?
- Are there any other ways of fixing this problem that do not involve Configurator 2, or wiping and reinstalling everything from scratch?

Many, many thanks for any help anyone can offer here - this machine is in use for time-sensitive projects, and I’m trying to avoid having to wipe it and restore everything from backups.

It seems from the article linked that the revive option in AC2 does indeed "update" the recovery partition but whether it will re-create and update it is another matter and only trying it would tell you.
Having said that I can't see it doing any harm to your system. That's just my opinion, you understand
Though you should definitely have full backups anyway.
