The current setup with the dgpu disabled when I'm docked is pretty workable, I've been able to hotplug/unplug the laptop and use it docked and undocked with no stability issues. I did notice a week ago that windows update installed an older set of intel drivers than what I was running without prompting. I didn't disable windows driver updates in DDU because Razer doesn't publish drivers for this model on their website, they say all drivers should come from windows update (sortof like how MS does with the surface lineup), so it could prevent me from getting updates for touchpad/wifi etc. I haven't tried this + changing the power management settings in the nvidia control panel because those settings seem to be universal and I didn't want the 1650 ti killing my battery life while using it undocked.
I did do a full DDU wipe and had them cohabitating, but that was causing the random system freezes while idle or web browsing.
