Can't turn off adaptive brightness - Power options broken? / WIN10 / Dell M3800

since a while I'm having a weird problem with my M3800 with QHD display without knowing what caused it. It might have changed with the last major Windows update, but I'm not sure.
When I got the computer I immediately turned off the adaptive brightness feature but now, after almost 3 years, it turned itself ON again. On top of that, all the regular solutions to turn it off failed on me because the sliders, buttons and checkboxes to do so are just not there. (as you can see in the provided screenshots - they're german though. but as you can see in the power options even there the slider for the brightness is missing)
It's the same case for the intel graphics adapter options... everything related to adaptive brightness is not there.
Does anyone know what happened and how I can turn my computer back to be usable without shining bright light onto the sensor?
✔ drivers are up-to-date
I'm also not sure if it correlates but the new power options of windows (balanced being the only one) also seem to be corrupt in a way since when I click on the battery symbol I am not shown the slider to choose wether I want to save energy or have full power.
Sometimes when I start the Laptop it starts with the real maximum brightness (unaffected by the brightness sensors' calibration). it's only then, that when I press the function key to lower it, it jumps down a whole lot of steps in brightness and pressing the button to increase brightness then will just increase it by a little bit since the sensor seems to be ON again and deems my environment to be too dark for maximum brightness.
When i run the power-troubleshoot thing in the windows settings right after starting the laptop (now still in real maximum brightness) the outcome is that it tells me, that the display is to bright - and then it activates the sensor. But still I got absolutely no option anywhere to turn that "feature" off manually.
Even if I end the SensrSvc Service which is in charge of this feature its function (brightness lowers in dim environments) keeps working.
I'm kind of lost here... any ideas?
"Bildschirm" means display/monitor - the only option here is when to turn off the display:
the windows settings only allow to activate nightmode - there's no checkbox for adaptive brightness:
no brightness slider here:
no power slider in this menu:
