Bios Modding with 2 Identical Cards

[hksr]

So I'm thinking about modding my bios' for my RX570s and RX580s. 

I have 2 identical cards for each, so if I mod one of them and something goes wrong that leaves me with a bricked card, is it as easy as copying the bios from the good card and reflashing the bricked one?  Or is there more to it than that?

Even if you only got 1 card each, if you just don't forget to make back up of your bios, that's OK.

Oh ok, so as long as I backup the original bios, I can always just revert back with a flash?

Yes.
