Thanks to phantomofearth for discovering this, follow him for more hidden features!
You will need to download ViveTool, which is a small app that will help us enable hidden features from Windows.

After you download ViveTool, you will need to extract the contents of the archive into a folder of your choice.
Right-click on the archive and then click on Extract all. Select Your Folder and then click on Extract. You will also need to provide some administrative privileges.

After you’ve done that, you will need to open CMD as administrator. Type the following command in CMD:
cd "your-location"
Then copy and paste the following commands:
Enable Live Wallpaper:
vivetool /enable /id:57645315
Enable Network Speed Test Button:
vivetool /enable /id:57703775
Enable Drag Tray Improvements:
vivetool /enable /id:56631583,56632969,58542295
Enable New Mobile Devices Settings Page:
vivetool /enable /id:56845155
Enable New Privacy and Security Settings Page:
vivetool /enable /id:57118881
You will now need to restart your computer, for the changes to take effect.
After the restart, you should be able to see all the New Features on your Windows 11 PC.
