Is minus 20 °C an acceptable storage condition for lyophilised survodutide?

The specifics, since they change the answer: minus 20 °C · survodutide.

Somebody stated this to me confidently and I would like to check it before repeating it.

I would accept a well-reasoned negative answer over a poorly sourced positive one.

Is this actually true, and what is the evidence?
