How can I change the clock frequency dynamically?

Question

In my program, there are different sections like each section does a different task and I am trying to use a different clock frequency for each section.
So, I want to know is it possible to do so?

Kindly help me,
Thanks

Hello, 
 The nRF52832 does not support frequency scaling. The CPU frequency is always 64 MHz. The reasoning for this is that can let the system spend more time in sleep when you have a fast CPU clock.
