⚠️ IMPORTANT ⚠️ By default, the Steam Deck does not have the ability to enable secure boot through the BIOS with signed keys and requires using a 3rd party tool to achieve this which is currently in an experimental beta phase.

As of right now, I would strongly advise against using this method until the current bugs are ironed out. I have reached out to the developer to help with development of the tool following extensive testing and discovery of bugs, and will be providing a tutorial on the channel in the future once the tool is safe to use.
