Can an HTTP request ever be non idempotent but safe?

I’ve been learning about RESTful HTTP methods and how a GET should be idempotent and safe.
At the end of this article, it shows a table listing the methods and if they can be safe/idempotent.
It seems as though some can be:

• Idempotent and safe (OPTIONS, GET HEAD)
• Idempotent but not safe (PUT, DELETE)
• Not idempotent and not safe (POST, PATCH)

Is it possible to have not idempotent, but safe?
