No, the only way to get Elena is through Layla's path, theres no separate Elena path or a specific point where you can go for Elena only... sadly you have to break Layla's heart, if you dont do it now it will be a lot worse later as MC will take Layla's virginity.
And by now theres no way to know if breaking up with Layla before taking her v-card will be the only chance to be with Elena or not, maybe if players take Layla's virginity Elena path is closed for good, we have to wait and see how Nyx will handle it.
