I've tried setting NoHeaderB true in \etc\opendkim.conf but it does not appear to work. header.b still appears in Authentication-Results. Tested with 2.10.3.
Note that NoHeaderB is loaded into the variable conf->conf_noheaderb but is not used anywhere in the code. At opendkim.c:10710 header.b is added regardless of this setting.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
