Firefly indemnity for Enterprise Customers - For weeks I try to get an answer

In the last weeks I have written many mails to different email addresses of Adobe, but not even received a reply. I hope Adobe will now answer my question here.

In short, I would like to know if there is a way for sole proprietors to obtain the indemnity for Firefly?

Ultimately, this leads me to the question of whether you are allowed to book the Creative Cloud for enterprise plan as a sole proprietor. I have received conflicting statements from Adobe about this:

At one point I was told it was no problem to book the enterprise plan as a sole proprietor. Elsewhere, I was told that the Creative Cloud for enterprise plan could only be booked if the company had at least ten employees.

My question relates specifically to the German market (sole proprietor = Einzelunternehmer/Kleinunternehmer).
