Dolby Vision to SDR converting problem

[shurikello]

This is the first thing I tried. None of the settings change the behavior and the encoding algorithm DoVi to SDR.
To make it clear, here is a small video with an example. There are scenes with Patrick Swayze in front of a bright window, the brightness is automatically turned up. Why - is not very clear, it is absolutely unnecessary. I need to turn it off:

P.S. HDR to SDR conversion works perfectly at the same time.
