Custom Bootstrap 4 scsss?

Question

Sass

For some reason, I can’t find something similar for the 4th version
https://getbootstrap.com/docs/3.3/customize/
I want to throw out 1/3 of everything that I don’t need 200%, download scss, correct it under my own names.
However, in the 4th version I found only this:

Answer 1

because the "manual" way works just fine.
npm i [email protected]
in bootstrap.scss we disable unnecessary components by simple commenting
in _variables.scss we make our own values ​​for variables.
