Is there a way to hold device in reset using ST-Link V2/V3?

I am trying to load into external flash but while doing this I need to have MCU held in reset.

You can connect to the chip with stm32cubeprogrammer which will effectively prevent it from running your program. There is also the "connect under reset" option, but I'm not sure if it holds NRST low or just toggles it momentarily.
