Can we choose which core runs RTOS?

[Bryght-Richard]

One application I'm looking at needs RTOS+SIMD core + bare metal core. Another needs RTOS core + bare metal SIMD core.

With ESP32-S31, is it possible to choose which core runs RTOS, or is it always fixed which one runs the RTOS?

Decently sure FreeRTOS by default runs on both cores. If you only want one, you can use the same tricks as with other dual-core ESPs (e.g. start a task on the core you want to be bare-metal and disable the FreeRTOS tick interrupt / all other interrupts)
