Disable HTML Development in version 8.1

Hello Together,

I am currently working on some custom API Points in One Identity version 8.1. As far as I understood it the compilation of the Angular and NodeJS components is per default disabled. I also checked the configuration parameter "HTMLDevelopment" to confirm that it is disabled.Everytime I compile my project in the API-Designer the compilation of the Backend is successfull, but then it runs the command npm - install and npm -build. We do not want to use the frontend, we only need the REST API points to be accessable. Is there another way to prevent the API-Designer from running the npm commands or am I missing something?
