Quick silly question on booking an award flight.

I am trying to do a business saver award in US for October (if you need more details let me know).

There are some choices where it is a mixed cabin and the mixed cabin is in the XN fare bucket. I have a Chase card, is it possible that this can be bumped up to E+ or higher with miles or cash, or when I use my chase card to pay for the award? Or is the flight/segement having an XN because there are no business/first class award seats open?

Thanks!
