Hello XDA users and Fire TV users, Amazon now blocked the adb shell pm disable-user command permanently. You can no longer block update packages 7.2.7.3/6.2.8.7 and higher. If you just updated your device without applying the system components updates, it should still work so avoid those incremental updates if you can while it lasts.
I'm currently running a Fire TV Stick Lite [TWRP Unlocked] (sheldon) on firmware 7.2.4.2 (PS7242/3515)
The pm disable-user is as follows from adb prompt:
pm disable-user com.amazon.device.software.ota
Security exception: cannot disable a protected package: com.amazon.device.software.ota
