So I've found this option in the RB17 Pro 2019 - is it possible to switch either of these options to run the laptop as if it just has a RTX2060 in it and no IGPU?

(see "Primary Display" and "Internal Graphics")
also this strange option out by itself:

any of you Notebook buffs out there care to explain "Mux" and "Muxless" to me?@hackness

I also saw these options in my unlocked BIOS and considered what they'd do, but Like @Thysanoptera I didn't have the balls to try it, lest I end up with a black screen that I can't see how to turn the iGPU back on. But I suppose a CMOS battery pull would reset it...

For what its worth, when I unlocked the BIOS on my Razer Blade Pro 2017 with 7700/1060, there was only an option for muxless. If you have the option of switching muxless to muxed, that would be a solid win as you could run the dGPU without optimus and increase framerates. What you should do is figure out how to navigate the bios blindly to reset to default settings (memorize or write down the keystrokes needed to reach load optimal defaults, save, and exit)

The GPU is physically routed to the iGPU before the signal reaches the internal screen panel. So no you cant go dGPU only. But using an external display port screen is basically the same.

Summary:
SG - switchable graphics, optimus works
iGFX - Nvidia disabled, removed from device manager, only Intel GPU visible, internal screen works, external screens don't work
PCI - Intel GPU disabled, only Nvidia GPU visible, internal screen doesn't work, external screens work.
Switchable graphics options
