You cannot update firmware / tinker with BIOS etc. I will cover this in a breakout session at re:Invent today: https://www.portal.reinvent.awsevents.com/connect/search.ww#...
You have full access to the machine, so you can update firmware / tinker with BIOS etc.
Then let the machine go back into the pool, and wait for it dial home.
There is some mitigation, but this is a major reason a lot of vendors do not do per second / minute bare metal.
