Finally found it. It's actually in:
Application Style
-> Window Decorations
-> Click the small icon in the lower-left of the selected decoration
-> Draw separator between Title Bar and Window
I also found you can get there directly by running:
$ breeze-settings5
in a terminal.

Hi Nikos,
The band is tied to the window decoration theme. If you change that in
system settings > window behavior you should be good.
Thank you,

In Plasma 5.12, there's a blue line under the title bar when the window
has focus. I searched for a setting to disable it, since it breaks the
"seamless" feeling of windows and looks quite ugly to me, but can't find
such setting.
Can I disable it?
