No, not yet. Physical attacks are out of scope for the TKey1, even if we have some mechanisms in play which try to extend the time and effort required to perform a successful evil maid-attack extracting the Unique Device Secret (UDS). See the threat model for the release:
The current casing is fairly tamper evident (it will break), but we do not yet use real, tamper evident sealing. We are looking at tamper sealing for future versions. And ways to further protect against physical attacks.
