You can add a panel which blocks the area for maximize and auto placement. See
contrib/uwmrc.example:

    [4] = [
        gravity = "static"
        layout = "vertical"
        x = 0
        width = -100 height=16
        maximize-over =  false
        [ type = `button
            text = "X"
        ]
    ]
