  Despite their use as cosmological distance indicators and their importance in
the chemical evolution of galaxies, the unequivocal identification of the
progenitor systems and explosion mechanism of normal type Ia supernova (SN Ia)
remains elusive. The leading hypothesis is that such a supernova is a
thermonuclear explosion of a carbon-oxygen white dwarf, but the exact explosion
mechanism is still a matter of debate. Observation of a galactic SN Ia would be
of immense value in answering the many open questions related to these events.
One potentially useful source of information about the explosion mechanism and
progenitor is the neutrino signal.
  In this paper we compute the expected neutrino signal from a gravitationally
confined detonation (GCD) explosion scenario for a SN~Ia and show how the flux
at Earth contains features in time and energy unique to this scenario. We then
calculate the expected event rates in the Super-K, Hyper-K, JUNO, DUNE, and
IceCube detectors and find both Hyper-K and IceCube would see a few events for
a GCD supernova at 1 kpc or closer, while Super-K, JUNO, and DUNE would see a
events if the supernova were closer than ${\sim}0.3$ kpc. The distance and
detector criteria needed to resolve the time and spectral features arising from
the explosion mechanism, neutrino production, and neutrino oscillation
processes are also discussed.
  The neutrino signal from the GCD is then compared with the signal from a
deflagration-to-detonation transition (DDT) explosion model computed
previously. We find the overall event rate is the most discriminating feature
between the two scenarios followed by the event rate time structure. Using the
event rate in the Hyper-K detector alone, the DDT can be distinguished from the
GCD at 2$\sigma$ if the distance to the supernova is less than $2.3\;{\rm kpc}$
for a normal mass ordering and $3.6\;{\rm kpc}$ for an inverted ordering.
