The first '--disk-password' has a trailing '\' because there are further args following it on the next line. The other '--disk-password' usage has no following args, so does not need a trailing '\'.

Thanks for your quick reply! I think my short comment cause a misunderstanding here, what I want to point out is that virt-qemu-sev-validate not support --disk-password options but I still can find it in the manpages. I think we should replace them to --inject-secret luks-key:passwd.txt.
