Unable to override GPU Affinity

Hey!

I’m submitting a Redshift render-job from Maya 2017, and my system has two graphics cards installed, one unsupported by Redshift. It renders just fine inside Maya itself, it just ignores the unsupported Geforce 760, and uses the 2070 RTX instead.
But when I submit to Deadline, any Redshift-job fails because it gives me errors over that card.
I’ve tried to disable that GPU through Local Slave Controls in the Launcher, and through Superuser in Deadline Monitor. I’ve also tried to target the different GPU IDs in the submission settings, so the job properties has “GPUsSelectDevices=0,2” included, trying to ignore GPU-1. (And other possible combinations).

But no matter what I do, I get the same error.
Any ideas on how to proceed?
