You could open the project root folder via File Explorer, then set the appsettings.json file Read-only, then when you update the file content programmatically, it will show an exception to prevent update.
Note
By using the above method, when you update the appsettings.json file via visual studio, it will show this prompt:
If you choose the "Overwride" button, you have to re-set the appsettings.json file Read-only.
Besides, when using System.IO.File class to write the value in the appsettings.json file, it will throw an exception (because the file is read-only). So, you have to use the Try-Catch statement to catch the exception.
