How to compile selfclosed tags to PUG?

Question

HTML

Good day,
there are: PUG files
I collect the output using gulp , the gulp-pug plugin
Task (it is hardly needed, but still) looks like this:

gulp.task('pug:build', function() {
  return gulp.src(path.src.pug)
      .pipe(pug())
      .pipe(gulp.dest(path.build.html))
      .pipe(reload({stream: true}));
});

For certain reasons, sometimes selfclosed tags are required, for example

<meta />
<input />
<img />

And pug always generates these tags strictly in the form:

<meta>
<input>
<img>

Google suggests that the arrangement of self-closed tags depends on the declared doctype (they say, put NOT html5 and it will be ok), however, this is not the case, I tried for example:
doctype basic
And other " old " doctypes - PUG stubbornly does NOT close the above tags .
I dug into the documentation , it says in black and white:

For example, whether self-closing tags end with /> or > depends on whether HTML or XML is specified.

I tried to prescribe already from hopelessness:
<?xml version="1.0" encoding="utf-8" ?>
The result is zero, the tag is NOT closed (
