It isn't different when you have `:header-args:elisp: :eval no' in the drawer.

I get the message `Evaluation of this elisp code block is disabled.' either way.

Caveat: I am running release_9.5.1-233-ged5335.

But a couple of things:

1) Be sure to refresh when introducing `#+property' lines. If you paste in a 
property line and then org-babel-execute-src-block, the property will not be 
acknowledged. AFAICS, property drawers do not suffer from this. 

2) Property drawers only affect the heading under which they are placed unless 
placed at the top of the file. And either way, it is an error to insert a blank 
line above a property drawer. org-lint will complain although the message may 
be cryptic.

3) You probably know this, but exports use `org-babel-exp-process-buffer' which 
may perform differently than `org-babel-execute-buffer'.
