Hello,

Is there a way to tell iPhone (e.g., 12 mini) not to fast charge its
battery via its iOS v17.5.1?

Thank you for reading and hopefully answering soon. :)

Those who are using a fast charger want to fast charge. All others take
the charger that came with the iPhone 12 or an earlier version. They are 5W-Chargers which is really slow.

Most people's phones last a couple days between charges and can be
charged overnight or topped up in the car or at work according to their situation.

I don't have numbers but I'd bet a large slice, possibly a great
majority, of people with fast chargers don't actually need fast charging.

No, not using the OS.

Take a USB-A to Lightning Cable and cut it in half. For the D0 and D1
wires going to the Lightning end, put in a voltage divider on each pin
using a 22KΩ & 33KΩ resistor (22KΩ from D0 to ground, 33KΩ from D0 to
+5V, 22KΩ from D1 to ground, 33KΩ from D1 to +5V). Do not reconnect the
D0 and D1 pins to the end going to the USB-A plug. Reconnect the +5V and
ground wires between the USB-A and Lightning ends of the cable. Now you
will have 2.0V on D0 and D1 and the iPhone will charge at 500mA. Use
heat shrink tubing to do a neat job.

Dumb advice of the month award.
