Simply program it without the bootloader. I have tested the Nano I/O pins under this induced condition - they are stable. I wanted to add this, code won't do anything once the Nano is at or below BOR, all the Nano is doing is seeing a reset, right as the voltage is around BOR, so it might try to start, see another reset, etc. I can confirm by test code, the Nano only managed to do one reset and part run, when down in that < 3v sawtooth waveform area. Keep in mind, that there is NO indication of any positive spiking of the Nano 5v supply (spiking above 5v) - this is why I am unconcerned with these conditions in my own inverter, Without a bootloader though That USB controller is unknown and likely glitching - no bootloader - then it can do nothing to the nano.   .
