Is there any way to turn off auto-aim? Or at least have a way to lock
on to enemies?
No, and no.
Free targeting is not currently an option in the game for auto-attacks and most Elemental Skills/Bursts. However, some skills feature ground targeting, which you can activate by long-pressing E, such as Fischl's and Amber's Elemental Skills.
Also, if you are a Bow user, you have the option to activate Aimed Shot by pressing R, which allows you to control the crosshair and move it exactly where you want to target.
Other than that, targeting seems completely random.
According to internal testing, this is how often ores respawn:
- Iron Chunk deposits respawn every 24 hours
- White Iron deposits respawn every 48 hours
- Crystal Ore deposits respawn every 72 hours.
In addition to those 3 basic ores that you can find throughout Tevyat, the specialty ores such as Cor Lapis and Noctilous Jade (both currently found only in Liyue) follow the Crystal Chunk's timer -- they respawn every 72 hours.
Don't forget to send your unused characters out on expeditions. Make sure to select the 20h option -- this yields the highest rewards and can be well worth it if you do not have the time to play the game much (3-4 White Iron ore, 7-8 Crystal Chunks). The current expedition areas that yield ores are Yaoguang Shoal in Liyue, Whispering Woods and Dadaupa Gorge in Mondstadt.
Do not forget about Shitou in Liyue Harbor! He sells a stack of Iron Chunks, White Iron Ore, and Noctilous Jade, and his shop refreshes every 3 days.
As Showsni mentions in the comments above, doing material farming rotations with your buddies is a good way to not only save time, but greatly improve efficiency in farming ores. As long as you are in close proximity to your friend while you or them or harvesting an ore, you will both receive the material when any of you picks it up. This means that you effectively have twice the mineral deposits you can farm as you have two separate worlds.

The community wiki and reddit has been full of misinformation and there has been no video evidence that chests ever respawn.
I tested this with an AR 7 rerolled account and collected all chests in the town of Mondstadt during my first day of playing.
Now, 2 weeks later, I went by the same locations and no chests reappeared.
However, it has been confirmed by support that chests DO spawn when your Adventure Rank is raised. They just do not respawn, ever.
This reddit thread has all the video proofs and customer support replies linked, and I urge you to take a read. https://www.reddit.com/r/Genshin_Impact/comments/jeov1j/the_truth_about_genshins_chests
