How to build bower_vendor into one file in yii2?

Question

Yii

There was a need to install a ready-made admin template (Zapili), however, there are too many files in the downloaded template in vendors\bower_components. The problem is that yii2 copies all these more than 60 MB to assets - which is not convenient, especially since I will not use most of this bower_components. I would like to collect several files, for several pages that would be easy, and with copying of which there would be no problems.
