  Collapsing supermassive stars ($M \gtrsim 3 \times 10^4 M_{\odot}$) at high
redshifts can naturally provide seeds and explain the origin of the
supermassive black holes observed in the centers of nearly all galaxies. During
the collapse of supermassive stars, a burst of non-thermal neutrinos is
generated with a luminosity that could greatly exceed that of a conventional
core collapse supernova explosion. In this work, we investigate the extent to
which the neutrinos produced in these explosions can be observed via coherent
elastic neutrino-nucleus scattering (CE$\nu$NS). Large scale direct dark matter
detection experiments provide particularly favorable targets. We find that
upcoming $\mathcal{O}(100)$ tonne-scale experiments will be sensitive to the
collapse of individual supermassive stars at distances as large as
$\mathcal{O}(10)$ Mpc. While the diffuse background from the cosmic history of
these explosions is unlikely to be detectable, it could serve as an additional
background hindering the search for dark matter.
