Bomb the walled in districts with titan serum gas canisters. Turn the majority of their population into titans, then, if possible, lock them in the districts so the island can be conquered more easily. I know they don't have Zeke for the fancy 'command activated' serum gas, but any of the other warriors could supply spinal fluid that would turn eldians on contact.

Since Pecke has been able to infiltrate one of the cities, they may be planting gas canisters. The only thing about that is that they don't seem to be at a technological level where they could trigger them all remotely. I'm sure they could set up timers, but that would take a lot of coordination and it would mean that they would need to be very sure about their attack. Once the timers would be set, they couldn't deactivate them without tracking down each serum canister.
