Hello @Anderson Rodrigues Cavalcante , Welcome to Microsoft Q&A!

You can modify the key resource SystemControlPageBackgroundMediumAltMediumBrush and modify the first two digits of the color "#FFFFFFFF" to change the transparency.

<Application
    x:Class="ContentDialogTest.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:ContentDialogTest">
    

    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.ThemeDictionaries>
                <ResourceDictionary x:Key="Default">
                    <SolidColorBrush x:Key="SystemControlPageBackgroundMediumAltMediumBrush" Color="#FFFFFFFF" />
                </ResourceDictionary>
                <ResourceDictionary x:Key="Dark">
                    <SolidColorBrush x:Key="SystemControlPageBackgroundMediumAltMediumBrush" Color="#FF000000" />
                </ResourceDictionary>
            </ResourceDictionary.ThemeDictionaries>
        </ResourceDictionary>
    </Application.Resources>
    
</Application>

Thank you.
