How to Enable Secure Boot on Steam Deck
Enabling Secure Boot on your Steam Deck isn't something you do directly through the SteamOS interface. Since Steam Deck runs a specialized version of SteamOS, it's designed to be pretty secure out of the box. However, if you're dual-booting or have specific needs, you might want to delve into the BIOS settings. Usually, you'd restart the device, press and hold the Volume Down button as it boots to enter the BIOS, and then navigate to the security settings to enable Secure Boot. Make sure you know what you're doing, though, or you could run into boot issues!

Honestly, just enjoy the Steam Deck as is. Secure Boot is more of a PC thing and the Steam Deck is optimized for gaming straight out of the box. If you don't have a compelling reason to mess with the BIOS, why risk bricking your device?
Had to enable Secure Boot for a project and it was a headache. Ended up not really needing it. Steam Deck runs fine without messing with Secure Boot, so unless it's absolutely necessary, I'd say skip the hassle.
