ISRs might only be interrupted by higher prio ISRs if interrupt nesting is supported by your MCU and enabled.  
But for very small periods of time interrupts might be disabled (globally) by FreeRTOS.  
It is possible to exclude ISRs from being covered by FreeRTOS.  
See the docs and e.g. [this](https://forums.freertos.org/t/priority-conundrum-unblock-task-from-isr-priority-max-syscall-interrupt-priority/9386) topic and/or the forum for details concerning the latter somewhat special use case.
