If you have all the files in the same vscode workspace folder,
then you could name your 'main' nim file you want to always run, main.nim
and set a global coderunner custom command (Ctrl-Alt-K)) in settings.json.
My pc with nim on it is dead atm so I can't check or test it, but my laptop has
this lua setting with which you should be able to tweak the path and file
extension to work on nim:
"code-runner.customCommand": "/usr/local/bin/lua ${workspaceFolder}
main.lua"
Run
I mapped the normal command (Ctrl-Alt-N) to F8 and the custom command to F9, so
I can be editing a non-main file and still run either it or the main.lua file.
The variables reference for vscode is here if you need further tweaking:

You can also set up multiple commented-out custom commands for different
languages and uncomment them to switch language.
