Hi Anna,
No, I have no experience in that particular GPU – but I have installed Nvidia drivers for other GFXs (and sometimes that is a tricky business, especially if the distro believes that nouveau is sufficient…)
Debian testing/Bullseye … isn’t that supplied with nvidia 430.64? According to https://www.geforce.com/drivers/results/153714 driver 430.64 ought to work!?!
Have fun!
