Not all power plans are available in all computers. Please see below and the tutorial. This depends on the particular computer and may depend on the operating system in use.

Try creating a Custom Power plan (Control Panel, Power). Power plans just control how much battery is used. That does not speed up your PC beyond its normal capabilities.

Note in the article that not all power plans are available in all computers. That is likely what is happening to you.

Here is a good tutorial for Power Plans.

To list all your plans:

powercfg /Q >"%UserProfile%\Desktop\PowerPlanSettings.txt"

Power Plan descriptions

Windows 10 provides the following default plans: Balanced - Offers full performance when you need it and saves power when you don't. This is the best power plan for most people. Power saver - Saves power by reducing PC performance and screen brightness. If you're using a laptop, this plan can help you get the most from a single battery charge. High performance - Maximizes screen brightness and might increase PC performance. This plan uses a lot more energy, so your laptop battery won't last as long between charges. Ultimate Performance - Only available starting with Windows 10 build 17083. Provides ultimate performance on higher end PCs. Custom power plan - These are only available if either your PC manufacturer (OEM) provided additional power plans, and/or you create a custom power plan. These are available to all users.

Normally, you could view all current settings of a power plan in Power Options. If you like, you could also output these settings to a text file. This can make it easier to share or show the power plan settings.

If you like, you can choose to include all hidden settings of a power plan, but these settings are hidden by default in Power Options since they usually do not apply to your computer.
