A few apps like Photoshop and Fusion360 keep my running Windows. The graphics card situation is also a giant pain in the ass, my laptop has a Radeon and a RTX 3080 and I can't get any kind of prime offloading to work. I'd really like to use the radeon unless i'm running something intensive that needs 3d acceleration, but i think I'd likely have to reboot to switch between them.
That leaves me running the RTX chip the whole time so the laptop draws about 40W at idle, when running windows it's more like 10W because the nvidia chip is completely off.
Oh that's a bummer. In my case, my system had a MUX switch, though I'm not fully familiar with it, it changed GPUs based on what the application demanded. It turned out to be a huge pain in the ass when the mighty Alienware turned out to be a bug riddled bloatware laptop and I had to disable the MUX switch to actually play games. Stuck with the dedicated GPU like you now, unfortunately.
I think the Intel/nvidia combo works (with a lot of caveats) but the amd/nvidia one seems way less supported. Not a massive deal for me as I mostly use it as a desktop replacement machine, but it does suck to only get about 2.5 hrs of battery life on the rare occasions that i'm untethered.
My alternate GPU was an Intel UHD
