I have Ubuntu 21.04 installed on my laptop. There is supposed to be a “Performance” option in Settings > Power Mode, but I am only given the options for “Balanced Power” and “Power Saver”, regardless of whether I am plugged in or not. How can I get the “Performance” option to show up?

I have the same issue. If these options are managed by GNOME power-profiles-daemon it could be because our hardware isn't supported.
To quote the link above
There are 3 different power profiles, a "balanced" default mode, a "power-saver" mode, as well as a "performance" mode. The first 2 of those are available on every system. The "performance" mode is only available on select systems and is implemented by different "drivers" based on the system or systems it targets.
According to this Post you should be able to do that with the Slimbook Battery Tool.
To install it you need to first add the apt-repository:
sudo add-apt-repository ppa:slimbook/slimbook && sudo apt update
Then You should be able to install it with:
sudo apt install slimbookbattery
That fixed this issue for me.
