You can access files on the device's flash just like you would any other file in python:
with open("/flash/my_config.json", 'w') as conf_file: conf_file.write(json.dumps(my_config_dict))
with open("/flash/my_config.json", 'r') as conf_file: my_config_dict = json.loads(conf_file.read())
I use JSON file for this. In my application class instance the config is a dictionary. You can call json.dumps() on it and write the result into a file.
Later you can read the string from the file and call json.loads() on the result to "create" config dictionary.
Consider NVS if storing integers is all you need.
