If you've wanted to have your Steam Deck boot up with something over than the handheld's logo, a beta update that's available to install will let you do that.
By going to Settings > System > Steam Update Channel > Beta, you can install this update that also changes the resolution when connected to an external display, saving you the hassle of doing this once your Steam Deck is plugged into one.
Enabling a different animation is a simple affair, where you drop a video into 'steamui/overrides/movies/' when in Desktop mode, and once the Steam Deck starts up, it will look for a video in this folder, and play it when the Deck next boots up.

It speaks a lot about how Valve is keeping an eye on the community's innovative efforts, with YouTubers bringing out unofficial ways to do this previously. With this amount of customization, it only makes us wonder what else we'll be able to do by the time 2022 ends.
