Is it possible to force the system tray to use one line/a specific maximum height?

I'm using Latte Dock and it's taking 2 lines, so I get 2 lines of icons that barely fit dock vertically and I see no option to change that from the widget settings.

Changing the panel height is supposed to change to one line, though I am not sure if this is valid for Latte.
There is no config for it, yet, but it is coming to Plamsa 5.20
