I really, really doubt a show that's just now finally finding its own voice and identity, and doing a splendid job of it, is going to shackle itself to one of Enterprise's clumsiest and least successful continuity elements. The Temporal Cold War was a mess, a story arc that the show's own writers only did under network pressure, never had a real plan for, and were happy to cast aside for good at the start of season 4. I have no doubt that Discovery's throwaway reference to the "Temporal Wars" was merely an excuse to avoid dealing with time travel altogether. We will not hear them mentioned again, any more than we did in ENT's fourth season after "Storm Front" ended.
