사용자가 ATT 프롬프트를 거부하는 경우 나중에 변경하기 위해 설정으로 보낼 수 있습니까?

Yes, it is possible to link the user into the Settings page to change this the ATT setting, if the user hasn't disabled tracking requests at the device level. Apple even mentions this here: https://developer.apple.com/app-store/user-privacy-and-data-use/.

It won't reset the prompt to show a second time, but the user can go there and manually change the toggle setting.
