Hello,
It`s not guaranteed to work but you can try and download the latest driver available on their website which is 431.36. If you browse their product they have listed an RTX 2080 8GB and have a newer driver for download in the video card support section. If they make. The driver for RTX 2080 also contain all the files and info for your GTX 1080. If they mod the driver in any way you should be good to go whit a newer version which is 431.36 is not the newest but it`s better than the one you are using.
Here is a lint to RTX 2080 support page.
