you must change it in the template itself...

    <Style Selector="Button:pointerover /template/ ContentPresenter#PART_ContentPresenter">
        <Setter Property="Background" Value="{DynamicResource Button.MouseOver.Background}"/>
        <Setter Property="TextBlock.Foreground" Value="{DynamicResource Button.Foreground}"/>
    </Style>

    <Style Selector="Button:pointerover /template/ ContentPresenter#PART_ContentPresenter">
        <Setter Property="Background" Value="{DynamicResource Button.MouseOver.Background}"/>
        <Setter Property="TextBlock.Foreground" Value="{DynamicResource Button.Foreground}"/>
    </Style>

Much of the Avalonia UI styling system corresponds to CSS styling approaches. So without knowledge of this technology, you may find the hints here helpful.
