TV child lock


I come from Shaw and i was able to lock my tv box after 00:30 until 7am weekdays and 1am to 8:00 weekends and had no issues kids watching TV. But now i switch to Telus optik and they have no such option. Does anyone had find ways around this to get this working or any other suggestion?

I know i can add a timer but this should be not necessary in the era of technology!
