Where is option "Archive PDF/A-1a (ISO 19005-1)" saved

Hi all,

When I first install LibreOffice, and open, for example, LibreOffice Draw, if I go to File > Export as PDF… I have an unchecked option that is “Archive PDF/A-1a (ISO 19005-1)”. Is there any way for me to change that from a file, for instance, a configuration file?

I also noticed that if I uninstall and re-install LibreOffice the previous chosen option was saved. Where is it save?

Any help would be appreciated.

In file registrymodifications.xcu located in LO user profile, look for the string starting with
