obviate
Make entirely moot
To obviate something is to prevent it by anticipating and addressing it in advance.
You obviate a problem by making it unnecessary to deal with: The new design obviated the need for manual adjustments.
The word implies removing an obstacle or difficulty before it fully materializes.
Slightly formal, it often appears with "need" or "necessity."
