If the encryption is correctly configured then that doesn’t matter. The only vulnerability that matters is in the encryption algorithm and that’s very difficult to brute force or get a vulnerability for. Though at some point you’re dealing with rubber hose cryptography where you have do deal with not knowing the password yourself.

If you build your own kernel, the fix is in Linux 5.10.272, 5.15.223, 6.1.190, 6.6.159, 6.12.113, 6.18.56, 7.2.10 and 7.3

I’d probably write a bash script that recursively goes through the disk and creates any folders it sees on another path, and when it finds a file it creates a corresponding empty file with the same name. If you want more info you could script some metadata tools that extract the info and create a dummy media file with the same metadata.
