how calibrate the battery MacBook Air M1?

Do not try to micromanage the battery charging/power system. The MacOS handles this task very well. Just plug in the computer when needed or when convenient to do so. Leaving the computer plugged in will not damage the computer or the battery.

Modern day Mac batteries do not need to be calibrated.
