Are you hoping at some point Nintendo will release a product that lets the Switch Lite connect to a Dock for TV play? It doesn't appear that's going to be the case. YouTuber Spawnwave did a teardown of the hardware, and found why connecting the Switch Lite to a Dock is technically impossible.
“It appears that the hardware that is needed does not exist on the board, which is a semiconductor that’s required to interpret video. So unfortunately for anyone who’s wondering if that would ever be possible if it gets hacked or something down the road, it does not appear to be the case from what I’m seeing.”
