Disable RST pin

Is it possible, using microPython, to disable the RST pin on an ESP-01S module?

No, you can not disable the RST (=Reset) pin. It is connected to hardware logic in the chip, which cannot be changed by software. Why so you want to disable it? If it is too sensitive, tie it to Vcc with a 10k down to 1k resistor.
Why do you want to disable it?

For my application a single device will wake the ESP-01 from deep-sleep via RST; after that subsequent signals from the device will be sensed by a different pin while the ESP-01 is awake. I don't want the ESP-01 to be rebooted via subsequent device signals.

It would have been easy if there was software control of the RST; now I need to use external circuitry.

BTW: Do you know if an ESP-01 maintains connection to a router if light-sleep is looped between router beacons?
