Disable Lean Input after importing Unity Package?

getting error: Assets\MoralisWeb3ApiSdk\Example\3rdParty\Lean\Common\Scripts\LeanInput.cs(172,30): error CS0234: The type or namespace name ‘InputSystem’ does not exist in the namespace ‘UnityEngine’ (are you missing an assembly reference?)

If I add the InputSystem package it breaks my other assets. Is there a way to just disable LeanInput?
