STM32F723VEY6TR rise time information?

Hello, we are working on a project using the STM32F723VEY6TR and have been curious about rise time information, especially so regarding the rise time information for SPI.

I have found some information on page 174 in the following datasheet:
https://www.mouser.com/datasheet/2/389/stm32f722ic-1851054.pdf

Is there any other information regarding rise times published for the STM32F723VEY6TR?

Any help or information regarding rise times for this MCU would be greatly appreciated.
