DnD automatically turns on, seemingly at higher speeds

I have an issue with my DnD which will turn itself on automatically at higher speeds, for example when I’m in the tram. It doesn’t matter whether I’m using my phone or not, cause it also turns on when I’m using my phone at that time so it’s not because it’s accidentally clicking on something while it’s in my pocket.

When looking at my DnD settings, everything is empty, there’s no person or apps allowed, no customizable Lock Screen, no schedule and also no smart activation so I have no clue why it’s turning on by itself.
