I'm not sure what you mean by excluding the app from being *loaded*. If you're saying that you have ERL_LIBS=lib and you want to exclude one application from the code path you can take advantage of the fact that ERL_LIBS can be a list of directories separated by colon (or semicolon on Windows).

This could be prettier, but you get the idea:
ERL_LIBS=$(ls -d lib/* | grep -v '/APP_TO_EXCLUDE$' | tr '\n' ':')
