About cv2.wechat_qrcode_WeChatQRCode GPU usage

I’m trying to use the cv2.wechat_qrcode_WeChatQRCode with GPU in jetson, is it possible to do so with solely build from source with CUDA supports?
It seems like cv2.dnn.readNet have a option to set setPreferredBackend and setPreferredTarget, what about the wechat_qrcode_WeChatQRCode?

nice idea, but currently not implemented.n
(also note, it’s not a single network under the hood, but 3 seperate ones (detection, superres, decoding)
