Best you can do is rapidly push the confirmation button during text bubbles, and skip the cutscenes. You’ll know you’re almost done when you get the MSQ with the Aether current as a reward.

I know what you mean, though. I was enjoying Endwalker a lot, but the second half of the moon was such a drag. The zone is so large and there’s just a lot of running around; and nothing particularly interesting even happens. It felt very much like they were trying to set up background and purpose for the Loporitts, but it came out as more like filler, filler, and more filler. I skipped every second of it on my alt out of annoyance.
