How can I remove the battery health without replacing it?
You can’t. If you are getting a battery health warning that means the condition of the battery is very close to failing, so if you don’t want to suddenly be left without a working phone in the near future replace the battery.
If you are driving your car and you see a warning that you are about to run out of gas, would deleting that warning, make the car drive further? Of course it wouldn't. Batteries are like gas. When they run out of their ability to hold a charge, they fail. And in some cases, they fail to the point, they swell and permanently damage your phone.
You can ignore the warning. You can't remove the warning.
