Help Samsung firmware modifications/Samsung custom firmware

Everyone who is viewing this post, hope will be doing well and safe. I need help regarding how to set Phone Status Custom to Official, in a custom phone without flashing the Official file. No need to guide me step by step just give a hint, so I can start. Waiting for your response.
