Whenever a dark page or a video gets too dark, the 2nd screen is automatically dimming, which can be annoying when watching dark scenes or browsing/editing with dark mode

How to stop it?

Itś a laptop

Built-in screen does not dim in any moment
Second monitor is a TV, connected via HDMI

TV dims with every display mode (mirror, extend or only external monitor)

TV did not dim with Windows 7/10/11, so it is not the TV

Itś running latest Bazzite KDE Nvidia RTX Series | GTX 16xx Series+ (bazzite-nvidia-open-stable-live-amd64.iso) plasmashell 6.6.3

Itś not caused by accidental touches on kb brightness keys

Display configuration > color accuracy > set to prefer color accuracy
Power management > dim automatically > set to never

I can't open this link which has the exact question, as it shows:

"Failed to verify your browser
Code 11"  

:/

Any help is appreciated, thanks in advance

The setting is actually under Display Configuration. Look for "Control hardware brightness with DDC/CI."
