It's not possible to modify an emulator to be seen as a phone, since the games that do check for emulators tend to utilize various variables to detect them: system properties specifically the android sdk, some games even go by simply detecting anything that runs on x86 architecture since no emulator runs on a true ARM64 architecture, physical component scanning and so on. Only way to bypass their detections are through reverse engineering the game's detections and extensive programming knowledge. Good luck.
