EXTI11 with SPI1 on STM32U575

I am using the gpio interrupt (EXTI) and trying to tie with SPP1. Only EXTI4_TRG and EXTI9_TRG are defined in stm32u5xx_hal_spi_ex.h for group1. 

Is that possible to define EXTI11_TRG in the group1?

No, you can only use triggers that are defined in the reference manual, and EXTI11 isn't one of them.
