Fast Refresh in production mode - React Native

Question

i am new to react native. i already build mobile apps which take configuration from ENV file. i use Config from react-native-config. but now i want to change value of some property in that Config file.

I managed to call hook and get data. let's say the data is "X" and i success to store "X" in "Config.name". but nothing change in my app. i had to do fast refresh in order to see the changing.

my question is, is it possible to do fast refresh in production mode? if not, how can i work around with this? i have to call hook in order to get the data first so i think it was the problem since i couldn't call hook when the app in prebuilt. so the app took value from ENV file instead of waiting from hook call.
