I'm on the stock cricket firmware. I enabled it with reg edits. I found two of them and have them listed. Tonight I'll reset the phone, make sure dbl tap is gone. Then will manually add those to make double sure.
With the way I enabled DTtW I have it in settings->extras->touch and under settings->personalization->Lock screen.
Another cool regedit trick I found, is changing the glance screen dark mode color to something other than red green or blue. It resets back if you make another change to glance in settings, but still cool to change it up
