Future Byzantine-Persian Wars in a no Islam Scenario

So we have had a lot of no Islam if then what threads recently.

The Islamic conquest began only a few years after the last Roman-Sassanid war.

If Islam is butterflied away or killed in its cradle then when would the next Byzantine-persian(not necessarily Sassanid) war be?

750? 780? 800?

What other forces could break the eternal conflict between them?

Or might one side achieve a decisive and lasting military victory over the other at any time from 750 to 1200?
