How can I stop my character from automatically healing?

Hey, I've seen in a few games that when you get damaged you don't heal automatically. For my game I think this would be a good idea but I cant find the settings inside the humanoid. I was wondering if you needed to script it but I've got no clue where to start since I don't even know the setting I am looking for. Could anyone help me down below? Thanks. Ill accept the answer if it works

When the player spawns, the game adds a script called Health to the character which you can destroy or enable/disable
