Bottles wine - how to force dgpu?

I’m trying to run GoG and some games through bottles, but the games all seem to use device 1 when looking at nvtop, and that happens to be the integrated gpu, not the discreet gpu. How do I get bottles to tell my running programs to use the dgpu?

With linux-native programs, I can just prefix the command with DRI_PRIME=1 and it works, but passing that to the programs running in bottles doesn’t work. I imagine because it’s calling the command in an emulated windows cmd rather than the host itself.
