In a simple binary phase diagram, according to the phase rule,

#Phase + #Freedom = #Component + 1 (pressure is fixed).

Then, the eutectic point will have 0 degree of freedom.

Does this rule apply to a spinodal decomposition as well?

Only once you have reached the final equilibrium concentrations, and it does
not apply to the interfaces, which are nonequilibrium structures.
