Can I remove windows’s ctrl+alt+paddot hotkey?

I would like to use ctrl+alt+paddot (the period key on the numpad) for a keybind in a game I play. Windows interprets that combination the same as ctrl+alt+delete though, so the game never sees it. I already have a perfectly functional delete key, and I don’t need a backup. Is there any way to disable the keypad version of the hotkey, so the combination can be used in applications?
