Turn off "Recently Deleted" album

You can't. If you want them deleted before the 30 day threshold, then you can go into that folder and delete them again. Otherwise, you can wait, and they will be deleted from that folder in 30 days.

Be aware, however, that there is a current issue with that very folder, and although you cannot see the photos in the Album anymore, they may still be on the device. To check that, go to Settings>General>Date & Time, turn off Set Automatically, and change the date to 9/1/2014. Then go back to the Recently Deleted album to see if there are any photos showing. Delete those before going back to the Date/Time and setting it back to Set Automatically. A fellow poster - txforever - discovered this solution.

This issue has been reported to Apple.

That "feature" was born of a thousand teeth-gnashing posts of people complaining that they had inadvertently nuked their priceless wedding/1st communion/graduation/etc. photos and how terribly cruel and inept Apple was in not providing some form of idiot safety net. So no, I do not think it will be going away anytime soon.

Welcome to the Modern World. That's what happens when you graduate way too many bloodsucking leeches…er…litigation-eager lawyers, year after year.

Tell Apple

Design for the lowest common denominator.

I'm inclined to agree with you 😟
