Hi
As the Cycles preferences are user based per machine, we have to provide some kind of option to choose between CUDA and Optix.
(And probably an option if CPU should be used as well)
We have to think on how we can achieve that.
Perhaps by choosing the renderer in the rrSubmitter (lower left).
And then as a next step someway to detect which renderer you have choosen in your Blender session.

or our support system for new questions.
FYI:
The next July update has a rrJob settings for Optix and CPU for Blender GPU rendering.
