How do I set Arabic/English keyboard on MacBook Air M2?

The Display language will be whatever you set it up to be when you set up the Mac.

Its not limited.

click here ➜ Set up your MacBook Air for new Mac users - Apple Support

The input language for the keyboard can also equally be changed from the Mac Settings and can be set to support both languages and change between them by tapping on the fn or globe key.
