Hi, I work on Stockfish! Likely what's going on is that your Lichess instance is running in MultiPV mode, which displays the top N moves (5 by default, iirc). This can be useful for analysis, but it leads to more time exploring disfavored lines, and therefore lower depth. The desktop version defaults to MultiPV = 1.
I also work on Stockfish, that is not the reason. The reason is because the SF17.1 is functionally different, there is no way to get these to match without changing the net option to be the same as the stockfish binary.
Viren's been around a lot longer than I have, so I'd trust him instead ;) You can actually run the large net in Lichess (by selecting the larger engine in the dropdown) which would be dispositive.
I don't work on Stockfish, but I can suggest using ShashChess instead. It is Stockfosh, but on top of that, it has been improved to capture the spirit of the human ingenuity and creativity.
Confirm in the network tab that you are going 100% local on lichess. My shot in the dark (I don’t contribute to their codebase) is that you’re offloading some analysis to Fishnet[1]

Most of Lichess is open source, have you tried looking there to see how Lichess interacts with Stockfish? https://github.com/lichess-org

I would rule that out first

One other thing I dug up that may help:
https://lichess.org/forum/lichess-feedback/groundbreaking-im...
Lichess uses a smaller net by default. Default lichess net is custom made by stockfish to be small
Have you compared the versions of Stockfish in each?
In Lichess I think you can also choose different eval nets. There's a small one and a big one. That will affect N/s.
Have you compared how many threads each are using?
Furthermore, Lichess Stockfish is a WASM build while your local Stockfish is a native binary executable.
Many have already mentioned number of variations will significantly affect time to a certain depth.
The lichess one might be in "multi-line" mode
