How about trying to create a change management process (supported by some time that someone other than your boss made a disastrous change)? Get him on board about how important that process is, especially when working in a team and something as critical as AWS. hint hint..

That's already in place. I personally use the Web Console as a read-only tool, but it's hard to keep a manager with past developer background away from poking around - policies are for the mere mortals! :)
