Welcome, @rbott.1, to the community!
No, it would only be possible either to switch off the supply voltage of the STM802 or, alternatively, to disconnect the reset output from the device to be reset.
STMicroelectronics also does not have a supervisor in its portfolio that can be disabled via a pin (which is also a little contrary to the function of a supervisor) - typically an MCU, such as the STM32, can monitor itself with functions such as IWDG and brown-out detection.
Good luck!
