How to disable Mac's generic Option-Command-W? [duplicate]

I end up accidentally hitting it because I have a similar shortcut for something else. I was hoping to disable Option-Cmd-W. I am fine disabling it only for one app specifically, or for all apps, whichever is easier. I'm on MacBook Pro, Catalina.

What software can I buy that could do it?

(Or maybe I just missed some menu option?)

Note: I'm talking about the shortcut that is set by Apple, not by any application. It's mentioned here: https://support.apple.com/en-us/HT201236. Chrome is not showing this key assignment in its menu (it has Close All listed in the menu, but it seems as if it's unassigned). And yet, when I followed the accepted answer, I did manage to disable this.

Solution 1:

If you want to change the keyboard shortcut for Close All on the File menu of Google Chrome, this can be does in: System Preferences > Keyboard > Shortcuts > App Shortcuts

Click the [+] button and fill in the sheet that appears.

For this example, I changed it to: ⌥⌘/
