I think you can use it as ZO_PreHook variant but ONLY for functions like UseItem() now.

Don't hook a non-protected function with this PreHook or game won't load

If you return true inside your PreHook UseItem won't be executed if I understand it correctly?

ZO_PreHookProtected('UseItem', MyUseItemFunction)
 
local function MyUseItemFunction(..)
   if doNotUseItem then
      return true
   end
end
