I think it's OK. @ventoy used Super UEFIinSecureBoot Disk files to disable UEFI file policy, that's the easiest way, but not a 'proper' one. However, I guess it should be possible to automatically enroll ALL needed keys to shim from grub module on the first boot (when the user enrolls my ENROLL_THIS_CERT_INTO_MOKMANAGER.crt) and handle unsigned efi binaries as a special case or just require to sign them with user-generated key? So, Secure Boot is not required for TPM-based encryption to work correctly. EDIT: This solution is only for Legacy BIOS, not UEFI. unsigned kernel still can not be booted. Unsigned bootloader Linux ISOs or ISOs without UEFI support does not boot with Secure Boot enabled.
