Using filtering option "-d NM:0" returned an empty set of alignments.
A few tests suggest that this is always the case for integer tags, while
filtering works as expected for tags of type string (Z).
(I use samtools Version: 1.10 (using htslib 1.10.2) installed by bioconda).
Yes, I'm afraid the samtools view '-d' and '-D' options currently only
work on string tags (type Z). No-one has implemented the type conversions
needed for integers yet, and to be really useful for them it would
probably want to be extended to do greater-than and less-than comparisons
as well as equality.
