Yes but at the end of the day you need to trust the cloud provider tools which expands the trust boundary from just hardware root of trust. Who is to guarantee they will not create a malicious tool update and push it then retract it? It is nowhere captured and you cannot prove it.
You can detect and prove it because the hardware attestation signature will change.
You might not know what change was made, or have any prior warning of the change. But you will be able to detect it happening. Which means an operator only gets to play that card once, after which nobody will trust them again.
