Is it possible to abort Iray rather than drop to CPU?

I've got a small form factor system, so the cooling system isn't spectacular. The GPU runs at a temperature I'm reasonably happy with when rendering, but the CPU does get hotter than I'd like when doing very intensive stuff, and really takes ages to do very little rendering.
Is it possible in the event that the render can no longer run on the graphics card to have it end the render instead of dropping to CPU? If that's an option, that would let me confidently leave it on while going out for a few hours.
(Yes, I do have CPU unchecked in the devices section, but it still drops to it).

Not as far as I know.
You could limit how many cores/threads Studio has access to, so if it does drop to CPU, then it would only use those; not sure if that would help.
If you want to limit threads, Windows 10 (can't remember earlier versions); Windows Key X > Task Manager > Details Tab > Studio > Right Click and Set affinity, then choose what to remove from Studio.
By limitint the threads, you reduce the amount of heat produced, and allow the system to do other things more easily.
Definitely not in the current vesion of Iray, but apparently nVidia does have it listed as a feature to be added to Iray 2019.x. That doesn't mean it will appear, and there'd still be adding that version of Iray to DS, but the possibility is certainly there.
Well, poop.
I guess it's not a mega big deal, but it would have been quite useful to be able to disable CPU rendering entirely.
I often end up doing that anyway to reduce the lag on other things, but it's a partial solution at best here - making the render even slower just makes it more frustrating that it hasn't aborted!
It would also be cool if you could "clean the VRAM" and make the render start from where it dropped, without losing any progress! Like if you had just started Daz again!
For example, since I've just one GPU, renders often drop to CPU when I watch a video on YouTube.
It would be nice if it resumed again on its own! ^^
My issue is it will freeze the computer up so I cannot even click on DAZ studio in processes task manager and end it, clicking on stop render is impossible task manager is my only option if I can get the mouse to move
If I know in advance going to CPU is likely I can right click and limit DS in TM
