  The Deep Underground Neutrino Experiment (DUNE) is an upcoming neutrino
oscillation experiment that is poised to answer key questions about the nature
of neutrinos. Lattice QCD has the ability to make significant impact upon DUNE,
beginning with computations of nucleon-neutrino interactions with weak
currents. Nucleon amplitudes involving the axial form factor are part of the
primary signal measurement process for DUNE, and precise calculations from LQCD
can significantly reduce the uncertainty for inputs into Monte Carlo
generators. Recent calculations of the nucleon axial charge have demonstrated
that sub-percent precision is possible on this vital quantity. In these
proceedings, we discuss preliminary results for the CalLat collaboration's
calculation of the axial form factor of the nucleon. These computations are
performed with M\"obius domain wall valence quarks on HISQ sea quark ensembles
generated by the MILC and CalLat collaborations. The results use a variety of
ensembles including several at physical pion mass.
