Yes. I have a GTX 1080 Ti in my 2400G rig (took some effort but eventually got the two to play nice).

Would you mind expanding on this topic? So my dad ended up getting a GT 1030 and the 2 HDMI from the 2200G work *until* the GT 1030 is plugged into the PCIe slot. At that point, nothing works if it is hooked up to the motherboard HDMI, but both of the GT 1030 ports work. Device Manager says the Vega from the 2200G has "error 43". We have tried cleaning out drivers and installing new ones with no luck. As soon as we take the GT 1030 out, the APU ports work just fine, but the idea is to have 3 working monitors for his book writing and video editing. We went through all of the settings in the UEFI related to the APU/Vega stuff and even after we force it to be on the ports refuse to work and Windows still shows an error. We started trying to get the 2200G and GT 1030 to work on Win 10 1709, but after we tried all of the previously mentioned stuff with no luck we moved up to Win 10 1803 and still can't get them to play nice.

Likely BIOS issue. Try to set up IGD as primary display device. If it is on auto, you can't be sure if BIOS developer did not disable it upon detecting 2nd GPU. Beware superfastboot feature, that disables some components upon detecting minimal set required to continue booting and leaves everything else to OS.

Thanks for the suggestions. We did get it figured out tonight. Looking through the BIOS, we had to change IGP enabled to auto instead of forced, and then the primary display adapter from PCIe or IGP to auto. Only after we put those settings on auto would Win 10 let us use the motherboard HDMI ports.
