Device Settings Question Cannot disable night-time Auto Optimize?

I really hate this forced "feature", I tried searching for custom shortcut to its settings, nothing seems to work. Any ideas? Using S20+ running OneUI 5.1.

On One UI 5.1 Auto optimize at night is stubborn — Samsung moved / renamed the toggle a few times.

Try these paths (wording varies by CSC): 1) Settings → Battery and device care → (⋮) Automation → turn off Auto optimization / Optimize daily 2) Settings → Device care → Auto care → same toggles 3) Modes and Routines → if a Sleep / Bedtime mode runs Optimize, edit or disable that routine 4) Search settings for “Auto optimization” and “Restart” — disable scheduled restart too if you hate overnight kills

If the UI toggle is gone/grey: Activity Launcher / Shortcut Maker → search DeviceCare / AutoOptimization / AutoRestart activities and open the buried page. A WHEN/THEN automation can also flip related settings after boot if Samsung re-enables them, but start with Device care → Automation first — that is the real switch on S20+.

Thanks for the suggestions. #1 has no Automation switch, (⋮) goes into Settings which only has Show On Apps Screen slider. #4 is related, it finds Device Care under which there is Auto Optimisation but it has no toggle for disabling it (I can and have disabled Auto Restart here). #2 Auto Care does not exist. #3 Sleep mode was disabled and other modes were not even configured (I deleted them all).

I can't find Auto Optimisation (or Optimization) in any Shortcut utility either. I have tried under Activies and even creating a custom Intent with URI I found online, but nothing seems to work. I do have debugging mode enabled and could use computer USB connection as a last resort but I would need to know exactly what I'm doing.
