Dual bank support on STM32G431

I've been trying to implement over the air updating on a board with the mentioned MCU. According to the reference manual of the G4 MCU series, dual bank operation should be supported, but the Flash memory characteristics of the G431xB series only mentions one bank. Furthermore "FLASH_OPTR_DBANK" is not defined in HAL, which suggests that it isn't an option. Does this mean that this specific G4 series doesn't support this operating mode?

AFAIK only the FLASH chapter for Cat.3 devices says that, and the 'G43x is Cat.2 so it has a different FLASH chapter.
