i have some plugin in my Webpack config:

plugins: [
    new somePlugin()
]

But i want does not start this plugin when i just run npm run start, but run if i add some flags, like npm run start --plugin for example. Is it possible to implement this without dividing the Webpack into different configurations?

You can do this by passing env variables with the webpack command

For Reference read this https://webpack.js.org/api/cli/#environment-options

run => webpack --env.production

Change the module.exports in webpack.config.js as this 

module.exports = function(env, argv) {
  return {
    mode: env.production ? 'production' : 'development',
    devtool: env.production ? 'source-maps' : 'eval',
     plugins: [
       new TerserPlugin({
         terserOptions: {
          compress: argv['optimize-minimize'] // only if -p or --optimize-minimize were passed
         }
       })
     ]
  };
};

Pass any env variable and use it to conditionally push plugins in your config.
