The experiment was documented in video that you find below, which reveals how the procedures implemented by the youtuber SpikeHD have not been simple at all, made possible even within their limits only by the fact that the Nintendo Switch used had been subjected to jailbreak.
The author of the video managed to install linux on Switch via a complicated system with SD and USB devices designed to prevent the console from initializing, so he had to short the Joy-Con connectors to complete the operation.
At that point, however, the platform’s NVIDIA Tegra chipset was fully confirmed incompatible with Steam applications, which made it impossible to install games. At that point, SpikeHD installed Android and a Steam Deck-style theme to console himself.
