Source blocks are indented

[<c.buhtz@posteo.jp>]

Hello,

#+begin_src python
  import sys
#+end_src

This example shows a python source block in an org(roam) file. Org
always does an indention here of two spaces.

Is there a way to turn this of?

It seems to me this is not the default behavior because I saw some
youtube videos where there is no indention in such blocks.

I'm using Emacs 27 (from Debian 11) with latest org and org-roam. I
minimized my init.el and still can reproduce it.
