Thanks for confirming.  I tried to enable it but ran into build errors:

https://salsa.debian.org/jas/nsd/-/jobs/8255756

As far as I some XDP objects are needed during linking, this patch fixed
it for us:

https://github.com/NLnetLabs/nsd/pull/460

With that it builds reasonable well:

https://salsa.debian.org/jas/nsd/-/pipelines/933804

Also, by default, it seems some *.o files are installed into
$(sharedfilesdir) which became /usr/share/nsd for me, see Makefile.in:

	if test -n "@xdp@"; then $(INSTALL_DATA) xdp-dns-redirect_kern.o $(DESTDIR)$(sharedfilesdir)/xdp-dns-redirect_kern.o; fi
	if test -n "@xdp@"; then $(INSTALL_DATA) xdp-dns-redirect_kern_pinned.o $(DESTDIR)$(sharedfilesdir)/xdp-dns-redirect_kern_pinned.o; fi

These are architecture-dependent files, aren't they?  Is there some
standard non-/usr/share location for these files that you could use?
This may be a Debian-specific concern, I asked the same here:
