I could be wrong, but I’m pretty sure that’s a different thing altogether.
Edit:
Yeah, disabling prefetch:

uBlock holds itself (ideally) to a higher standard than not executing js or hiding an element, it tries to prevent the network connections from even taking place. This is for browser prefetching that happens on many pages even after the environment and extensions are fully loaded, in many different contexts, to speed up requests by having the binary payload of the response already available in cache before it is needed.
