Hi.
I’m sorry for the delay in my response.
I’m not very experienced with this subject. But I think you need to create different tasks with different priorities. See the dual core unit for more information: https://rntlab.com/module-12/esp32-dual-core-create-tasks/
When creating a task, you can define its priority:

xTaskCreatePinnedToCore(
      Task1code, /* Function to implement the task */
      "Task1", /* Name of the task */
      10000,  /* Stack size in words */
      NULL,  /* Task input parameter */
      0,  /* Priority of the task */
      &Task1,  /* Task handle. */
      0); /* Core where the task should run */

I’m not sure if this is useful for your project.
I also answered your other question here: https://rntlab.com/question/interrupt-allocation-to-core0/
Regards,
Sara
