Unfortunately, HAL could not be modified.
It is used as is and if an issue is identified then it have to be corrected first in the HAL driver; feel free to raised an issue on the related GitHub:
https://github.com/STMicroelectronics/stm32c0xx-hal-driver/blob/c283b143bef6bdaacf64240ee6f15eb61dad6125/Inc/stm32c0xx_hal_gpio_ex.h#L64
If it is a blocking issue then a workaround can be added in the stm32_def.h as it is already done for an other missing AF:

#if defined(STM32C0xx) && defined(USART3) && !defined(GPIO_AF7_USART3)
#define GPIO_AF7_USART3 ((uint8_t)0x07)
#endif // STM32C0xx && !defined(USART3)

#define GPIO_AF0_USART2 ((uint8_t)0x00) /*!< USART2 Alternate Function mapping */
#endif /* STM32C031xx | STM32C071xx | STM32C091xx | STM32C092xx*/
#if defined(SPI2)
