But in dietpi-config it will show:

dietpi-config works, so you can/will overclock or underclock RPi Zero, but I think, do this, it is not correct. Read on raspberrypi.org form the developer, no over-clock options are presented in raspi-config as the stock 1000MHz settings are at the upper end of what the majority of the hardware is capable of.

Tested, with raspi-config, where is no overclocking option.

I think, undervolt and underclock will be okay,for people want to save power consume. It's no will damage your hardware.
But overclocking will not be a good idea, just as RPi3.

So better will do something like that:
