How to solve a keyboard shortcut conflict between the Finder and Word for Mac on Sonoma or later?

I have a conflict between Finder and Microsoft Word with the key combination Shift + Command + D. Finder uses it to open the Desktop window and this prevents me from using this shortcut to toggle Dark mode in Word. To clarify: if I use this key combination, Word will not toggle Dark Mode even if it has focus. If you return to Finder, it can open the Desktop window as usual. Therefore, the problem is not the keyboard. I am running macOS Sonoma at work and macOS Sequoia at home. I only find this problem in the computer at home and **none of the old solutions work**, including: 1. Edit the Finder shortcut in Apple Menu -> Settings -> Keyboard -> Keyboard Shortcuts system control panel. Although the conflict disappears then the new shortcut I chose for Finder works the first time but it won't work later (a bug?); consequence: I needed to reverse this setting. 2. Tried to use many apps to edit this **pre-existing** command in Finder that are able to edit keyboard shortcuts but due to the changes how this is achieved on Sonoma and later editing the com.apple.symbolichotkeys.plist does not work anymore and none of the apps in the market are able to edit these **pre-existing** key combinations. (I am aware that these apps are able to add new key combinations but they are not able to **override** pre-existing Finder key combinations, though). The only app able to **override** any Finder keyboard shortcut is the System Preferences panel I referred to in 1. Moreover, some of the apps even require privileged helpers and I do not want that. *What do I have to do to solve this conflict?*
