Other HW that allow you to export digital backups: Bitbox02, Coldcard, Keystone (correct me if I'm wrong).
The bitbox doesn't encrypt the backup, I think they keep the seedphrase in plain text (I never inserted the SD card with the bitbox backup into the PC, only into the bitbox).

But as long as the user is using passphrase, even if someone has physical access to the SD card containing the bitbox wallet backup, the attacker will never have access to the funds. However, I liked the passport backup method better (I believe coldcard uses the same method), as it keeps the backup encrypted in a 7zip file.

Encrypted backups with a sufficiently secure password help to duplicate backups more easily, as they remove points of failure, because even if the attacker has physical access, he needs the password to access the wallet.
