Skip dynamic wallpaper options in Sonoma?

[cwcampb]

Is there a way to skip the "Choose your walllpaper setting" in macOS Sonoma when a new user logs in? We have set a standard desktop background that we want to use across all our computers.

I should mention we don't want to use a profile to lock the desktop image across all computers since we have an admin account which uses a different wallpaper. Is there a way to just skip this preference in a Apple Setup Assistant Profile? What are the new Setup Assistant options for Sonoma?

Create a custom profile with the preference domain: com.apple.SetAssistant.managed with this payload. 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>SkipWallpaper</key>
    <true/>
  </dict>
</plist>

This will supress the prompt (and with 14.2 will leave the default wallpaper the same.

Thank you for sharing the key value. JAMF now needs to add this checkbox to prestage settings.
