I don’t think there is a way to cast an entire array’s contents easily. You could try this method, though:

TArray<AActor*> ActorArray;
TArray<ASomeActor*> SomeActorArray;
UGameplayStatics::GetAllActorsOfClass(GetWorld(), ASomeActor::StaticClass(), ActorArray);
for (AActor* UncastedActor : ActorArray) {
    SomeActorArray.Add(Cast<ASomeActor>(UncastedActor));
}

// SomeActorArray is now an array of ASomeActor.

Beware, don’t run this every frame as it is somewhat expensive to run.
