You can’t unfortunately. More info on this thread: https://developer.apple.com/forums/thread/766644?page=1

Hello, could you please check if there has been an update on our bug reports? They show unchanged on my side, but I am under the impression that something has been changed with iOS 26 / 26.1 / 26.2 beta. This is my radar from October 2024: FB15544362 [quote='822829022, Engineer, /thread/773290?answerId=822829022#822829022'] There's no supported way for you to customize the picker with the APIs currently available.

I’m curious what you mean with that. im also sometimes under the impression that my device is cursed when it comes to screen time, because there are so so many bugs. But then again, it’s not just me: we get user reports every day with complaints about bugs related to the Screen Time API. [quote='868587022, kgaidis, /thread/809410?answerId=868587022#868587022, /profile/kgaidis'] odd side-effect due to my device state [/quote]

Not for us, unfortunately. The issue is present throughout iOS 26, 26.1 and 26.2. Multiple radars filed already, but no response / fix in sight. [quote='868578022, kgaidis, /thread/793747?answerId=868578022#868578022, /profile/kgaidis'] iOS 26.1 seems to maybe have fixed it [/quote]

Unfortunately this is still unresolved on the latest iOS 26.3 beta. fingers crossed for iOS 26.4
