Can I control what backs up/syncs to Murena account

Greetings.
Now after one year with a Fairphone 3 and e/os I am still missing this very option.
Unlike described in the following post:

There is no such option /checkbox for me.
I missed this already in the beginning in April 2021.
I even reflashed my phone in June but I was still missing it. Idk why I left it this way, because I hate when my files get sync without my knowledge.
I saw this by accident last year and gave up after some days.
Now with version 1.0 I have a never-ending notification that rings every 30 minutes and isn’t removable.
