Indeed, this seems not possible at the moment.

I use options DKWEDGE_AUTODISCOVER and DKWEDGE_METHOD_GPT, but this only
"takes over" the bootdevice I already loaded the kernel from, so works
for "config netbsd  root on ? type ?" but not for hardwiring the config
to dk0.

I wonder if you could hardwire it to sd0 instead and dk0 would take it over
from that?

This is a bug and needs to be fixed.
