Answer 1

It doesn't meter where is your file is. The point is to include your custom variables before variables from bootstrap.

You can create BS file, where you can include BS components and other elements and in this file you can override default variables.

More over, in this case you can optimize your target CSS file.

One more thing - in example I using BS5, in v4 approach the same (because it's SCSS).

Your structure:

.
└── scss/
    ├── _bs-variables.scss
    ├── custom-bootstrap.scss
    └── custom.scss

Example:

_bs-variables.scss:

$primary:       tomato;

custom-bootstrap.scss:

// scss-docs-start import-stack
// Configuration
@import "~bootstrap/scss/functions";

// override default variables
@import "./bs-variables"; // here is your custom variables include
// default BS variables
@import "~bootstrap/scss/variables";

@import "~bootstrap/scss/mixins";
@import "~bootstrap/scss/utilities";

// Layout & components
@import "~bootstrap/scss/root";
@import "~bootstrap/scss/reboot";
@import "~bootstrap/scss/type";
@import "~bootstrap/scss/images";
@import "~bootstrap/scss/containers";
...

custom.scss:

@import './custom-bootstrap';

// other SCSS code
