On the Steam Deck? Possible. On Steam? I guess technically possible if you add a third party game. But actually on Steam? Nintendo can’t even give a tech demo out for free, I can’t imagine what would have to happen for Nintendo to put their games on Steam.
You can also play Minecraft on the Steam Deck and technically you can also play Apex Legends on the Deck (if you install Windows and play through that), but all of it depends on the user being a tinkerer. But the casual gamer is not a tinkerer which means those possibilities have next to no impact on the wider market.

I have a feeling there will be an increase in tinkerers as the cost of staying casual continues to increase to unreasonable levels.
