Hey, i'm opening this issue up and raising it again.
Since the time this solution was presented here,

the Swagger UI folks created a built-in option to disable the "try it out" button altogether.

Here is a reference to their doc which includes this option, and here's the thread (THE SAME ONE that raised that plugin work-around fix) with a comment down at the very bottom that says "hey, this work-around plugin thingy is no longer needed, since it is now built-in", and here's another.
I would love to see the support from the swagger-ui-express side as well! ❤️

Could it please be implemented here as well?
--- UPDATE ---
I tried it, it works 100%!

I passed tryItOutEnabled: true to the swaggerOptions, and now the "try it out" button is automatically clicked. The plugin override is not needed anymore. The built-in solution works great.
          
Those options can be set already via the swaggerOptions and will be passed through to swagger-ui:
