Try something like this in the nodes. It has some problems in some cases but overall it works significantly better than stock OIDN (Noise wise)
you can probably get away with using only 3 denoise nodes after the adds. It behaves weird on transparent objects like glass and transparency but still dose a decent job with the cleanest images you have ever seen 
Oh yeah plug the denoising normal in. I forgot to do that in this screenshot
