How to unbind Alt + ` (Backtick) on Windows 10?

In Dota 2, there’s something called Smart Double Tap, making Alt + Hotkey to work as if I’ve double tapped the Hotkey, and I have the Hotkey set as backtick `. But it seems like it’s conflicting with Windows Default Hotkey and the smart double tap isn’t working on that hotkey. I have another shortcut as space and smart double tap is working fine on that one.
