For binNMUs you'll need to pass "-B" at least, but see below.

Not exactly. The source packages are not changed for binNMUs. This is
handled via sbuild's --binNMU-* options to set the changelog and the
version. Specifically, these options imply that Arch: all binaries are
not built.

binNMUs are handled a layer above. sbuild will pass the correct options
to dpkg-buildpackage to build binNMUs. If you are interested in having
binNMU builds for your own infrastructure, you'll probably need to take
a look at the sbuild source to see how it is implemented.
