Personally, I would rephrase this to:

"Please note that, as an end user, there are currently no in-tree drivers
or modules suitable or intended for production use."

Also, I believe this should go here and not in Quick Start. The average end
user, to whom this sentence seems to refer, typically begins his/her
learning journey from the index page of our website.

I think this will be helpful.
