Razer as my streaming partner/promotion

Dear Razer
I am a YT and twitch streamer, not much famous yet but is it possible for me to put razer banner/logo on the stream while gaming basically like a sponsor but in return i am not asking to get paid/get any products i am just doing this because it will motivate me to grow more , i like razer products as i have been using them for my gaming/stream. So i just wanted to ask for permission if is it okay to put a razer banner on stream.

Best regards
