After a long time of users asking, Valve has actually added an official Battery Charge Limit setting in the latest Steam Deck Beta update so you no longer need to use third-party tools.
I think since the beginning if plugged in for some time it decharges to 95% so you are probably fine. You can check the battery health in desktop mode.
