This allows users to specify one or more certificate file paths or directories to be used during secure boot. Each entry is specified using the syntax: boot-certs..path=/path/to/cert.pem Multiple paths can be specify using array properties: boot-certs.0.path=/path/to/cert.pem, boot-certs.1.path=/path/to/cert-dir, boot-certs.2.path=/path/to/another-dir...
