2080 cards are not supported by the version of Iray included in DS 4.10, you need to use 4.11 beta.

Here’s the link to the store page for the beta: https://www.daz3d.com/daz-studio-beta

You need to “purchase” it first, then use Daz Install Manager to download and install it. You may need to change the parameters in DIM to tell it you want to see the “public builds” among the files to download, I don’t remember if they’re displayed by default

Where are you looking in Task Manager? The default listing in the Details tab doesn't show the Compyte_0 usage, which is how Iray is listed - if you go to the performance tab and chnage one of the graphs to Compute_0 (or CUDA) does it show full or partial usage?
