Disable minify for one bundle

Hey guys,

does anyone knows if it is possible with #aurelia-cli to disable minification of code for a specific bundle?
My problem is that the library Preact throws an error when it’s minified because of an undefined variable.
Therefore I would like to put it in another bundle and only enable minification for the other bundles.

I don’t want to look at the code so maybe someone can do this for me or knows this^^

Thx in advance
