Combinable incentives?

I’m using the calculator for a Nissan Ariya and I see the following incentives listed. I want to know are these combinable? There’s 10,000 NMAC for 25 months and 7500 NMAC. In the past when they had 18 month deals the 7500 was combinable with the ~3800 for the 18 months.

Can you click and select both?

My guess is they’re not stackable.

You are able to select both, but I don’t believe they’re combinable either. Would make for some insane deals.
