Gt 710 (kepler) not working OOB with Big Sur (but did with Catalina)?

I'm having issues with this GPU. I had no issue switching a 5700 xt out for it with Catalina. I didn't even change any boot args, kexts, or anything. With Big Sur, I just get 'no signal' when trying to use the card.

I tried messing with the boot args bit , system ID, etc., but nothing. Does anyone know why this would be happening?

It boots with nv_disable=1 , but disables acceleration obviously.
