You can find the setting under SW Setup in the Menu. Peaking Color is where you can set the peaking color. Peaking Level is where you can set the degree to which it shows peaking. When you scroll down to Focus Assist 1 you can set it to Both, Peaking, or Expand. When set to Both it will blow up a section that you can drag around and show the peaking of the magnified section. When set to Peaking it will not magnify a section it will just have focus peaking. I hope this helps.
