How Do I Buy Tickets for This Specific Section at Astros Games?

I have a question, I’m planning to attend an Astros game again soon, and I’m interested in sitting in the area circled in the seating chart I’ve attached. But I don't see a option to purchase the tickets through the standard single game ticket button on the official Astros website, Does anyone know the best way to buy tickets for this section? Are these seats available through standard ticket platforms, or do they require a special process to purchase?
