No way to set SysTick to -1 priority in STM32CubeMX

I'm using STM32CubeMX (V4.12.0) and targeting an STM32F411.

By default, SysTick has an IRQ number of -1 which makes it higher priority than an interrupt with Preemption priority of 0, SubPriority of 0. I would like to leave it this way.

However, STM32CubeMX modifies SysTick to have a priority of 0.

How do I tell STM32CubeMX to not change SysTick's priority?

My mistake - there is no issue. I confused the concept of IRQ numbering scheme with interrupt priorities.
