Hi Wei,
So, I can verify that this works all the way into Linux userland
dmidecode on arm64.
One question:
This set still leaves the -smbios set of options x86 only.
Would

be relevant to add here (6/6), and would that then be expected to work
for filling in values via command line (because that does not
currently appear to be the case).
