You certain? You should have it. I have a very similar setup to you. Nvidia 3070, PopOs on a laptop with Gnome. Its kinda hidden in the app. There is an advanced button that hides the option.

The lesson I think is only buy devices with local apis and avoid google services entirely. I have tons of smart devices in my house now but I require local control and they all sit on an isolated VLAN with no internet. The nest is the last remaining device that I haven’t switched over yet. Its 8 years old, I didn’t think about any of those things 8 years ago. Live and learn I guess.

Nest was towards the bottom of my degoogle list. I guess they are doing it for me. We hardly used the app anyways. I’ll just disconnect it from the network.

Try opening the Nvidia control panel, turn off Force Composition Pipeline. I had this same issue.
