I am using VENDOR_CERT_FILE,This shim could load grub, bzimage, but we have custom code in grub where we will verify initrd using detached signature using verify_buffer pkcs function. getting error: Unexpected error 0x8000000000000002. I am doubting shim overwrite start and load functions, and shim protocol does not take detached signature. is there a way to solve this issue.
