SceneManager.LoadSceneAsync Buttons in previous scene are still interactable

ON UI button i am calling SceneManager.LoadSceneAsync() . Everything goes well but if if click on same button multiple time it tries to load new scene multiple times.
Is there any way so that old scene become non interactable. As it should not call SceneManager.LoadSceneAsync multiple times.

 

The whole point of LoadSceneAsync is that it loads the new scene but keeps the existing scene running. So if you are calling LoadSceneAsync from a button you should disable the button yourself after the first press, or otherwise ignore follow up presses of the button.
