How can I prevent the conversion, <br> into <br />?

Hi, guys:

<br> tags are converted to <br /> after rendering.
How can I prevent the conversion?

*I know that the slash is mandatory in xhtml.
I’d like to follow the HTML Living Standard.

Can you please provide code along with Jekyll version you are using.

Thank you for the response.

jekyll build with v4.3.1

Jekylll uses Kramdown which seems to be following XHTML standard. So it seems, br /> is how it is going to be rendered.

Thank you for the information.
I understood the situation.
