I think he has an older bike with boost QR, not the pic that I posted which is TA. However, in the absence of input from the OP, I assumed the dropouts were similar. If the hub is convertible, that would be the best path by far. Rear TA is not much of an advantage on the rear of a hardtail, which is why manufacturers stuck to saving $1 per frame with QR. Now they have come to realize that their customers would prefer TA, so the QR is mostly gone.
