The Steam Deck, like most mobile devices, don’t have issues with voltage as most don’t deal with it. It’s their charging cables that do that, which are external.
In the Steam Decks case, you just need a plug adapter as the stock USB plug that comes with it is rated for 110-240 volts. Your voltage is 230 volts, so no problems.
I’ve already had to do this, so already know it works. I’ve used my Canadian Steam Deck (110 volts) in Ireland (230 volts), and well as in Korea (220 volts). All I needed was a plug adapter, not a voltage adapter.
If you are still worried though, the Steam Deck is powered completely through USB C so you could just get a different USB C adapter to charge it. The stock plug charges at a rate of 40 watts, but can go slower though charging speed will show.

Voltage won’t be an issue, it’s just USB c
