You'd have to ask that the people at Atmel.  If the /RESET line
defaults to be pulled while no software talks with the Dragon, then it
won't be possible.

The point is, the software driving the Dragon essentially establishes
a session: it has to say "Hello" to the Dragon, only then it can tell
the Dragon about its intentions (i.e., select between JTAG access, ISP
access, HVSP/HVPP access, or debugWire emulation), perform the
required actions, and the Dragon is usually quite upset if you don't
send him a proper "Goodbye" to end the session, so you gotta do that
as well.

So whatever the Dragon is doing /outside/ a session is beyond software
control.
