I did not know this, it looks like a solution in sight. Thank you.

By doing this:

@@latex:\def\version{@@ {{{version}}} @@latex:}@@

Then {{{version}}} will get expanded in the document, right? As I have
hidden then only tags surrounding {{{version}}}.

I have tried this:

#+OPTIONS: @@html:title:t toc:t@@ @@latex:title:nil toc:nil@@ todo:nil

But it is not working in options. It would be good if it works in OPTIONS.
