user29876: I have heard in various places that we can make engines play against each other from a certain given position. I want to know how exactly to do that. Is there a website where I can put a position and make Leela and Stockfish (14 or 15 preferably) play a position that I want them to play, or is it something only a few people have the advantage of doing?
Please let me know whether there are ways for me to arrange for such games.

user33889: Arena seems to be a good fit for what you want to do. You can install any engines you want, set up any position and make them play against each other using the Game->Demo command.

user825: Try:

https://github.com/cutechess/cutechess

You will see a sample usage where two engines are paired togerther:

cutechess-cli -engine cmd=sloppy -engine cmd=sloppy -each proto=xboard
tc=40/60 -rounds 10
