Can I have ResearchGate organize peer review of my paper?
I think I understand your question now. You've uploaded your article to ResearchGate, and ResearchGate asks you whether it has been peer reviewed. It hasn't, and now you're wondering whether ResearchGate can get it peer reviewed for you.

The answer is: it can't. It just wants to mark articles shared on RG that have been peer reviewed elsewhere as such, but it won't have it reviewed for you. To get it reviewed, you would have to submit it to an actual journal.
