I like to leave my Macbook Pro (2021 with Monterey 12.0.1 plugged in when I'm not using it. Unfortunately, every time it reaches a full charge, the power chime sounds. It seems to lose a little power from being in sleep mode, so it has to top off the charge after 3 or 4 minutes. This means the @#$#@!! chime is in hysteresis, sounding every few minutes repeatedly each time the Macbook returns to a full charge.
How do I disable this?

You can try unplugging the power adapter from the mains for a bit to reset the internal circuitry of the magsafe.
If your MagSafe cable or power adapter isn't working - Apple Support
Since there is no SMC or NVRAM on the M1 SoC...
—The best you can do if you have an issue— equivalent Shut down, close the lid 30 secs+ , reboot as normal.
