You Can't.

What you are looking to perform is not an option. This is because its hardware is not proficient enough to run it.

See Here: macOS Big Sur is Compatible with these Computers - Apple Support

Your device can update to Mac OS catalina. Follow the instructions by EU Rouge to get an installer for older OS versions:

You can ignore the other post. It refers to OS Big Sur which is irrelevant.

Babowa is correct: OS X 10.11 I did not see the "10" in "10.11". Took it as macOS 11

10.11 is El Capitan.

Big Sur is OS 11.
