  Controlled dynamical probe measurement of complex order parameter
fluctuations may reveal its massive collective excitations. Here, we design
dynamical quench protocols to excite independently all ten midgap Higgs bosons
in the isotropic Balian--Werthamer state of a spinfull $p$-wave superfluid or
superconductor. The analysis is based on microscopic equations of motion of an
SO(5) pseudospin, an extension of the usual Bloch equation to a five
dimensional space. Key to these protocols is the realization of quenches that
break the rotational symmetry of the kinetic energy and exploit the irreducible
representation of the angular momentum $J=2$. For perturbative quenches, we
find (non-decaying) periodic oscillations in time of these Higgs modes.
Experiments to realize our proposal for either superfluids or superconductors
are considered.
