The GTX1650 uses the Intel GPU for all video output, so its setup is the same as it is for integrated graphics -- the manual says three displays (internal + 2 external or three external with the internal display disabled). The system you have cannot use the nVidia GPU to output directly -- that's why the version of your system with the RTX GPU has support for four rather than three displays (it does have the option of using the nVidia GPU standalone, which the GTX version cannot). One of the Dell thunderbolt docks like the WD19TB will do the job.  
I have a Dell XPS 17 9700 laptop that I now will be using as my primary workstation. I currently have an EliteDisplay E272q and now this laptop will be my primary workstation. I have two more of these displays, that I want to connect to the laptop, probably through a dock. Would this be possible to get working? My laptop has the NVIDIA GeForce GTX 1650 Ti graphics card, so it's the medium option for this laptop. The External Display Connection Guide states that : "On computers with the NVIDIA GeForce RTX 2060 graphics card installed, you can connect up to four external displays or two 8K displays by enabling the Direct Graphics Controller Direct Output Mode in the BIOS." But what options do I have with the GTX 1650 graphics card, and can I even use my 3 current displays (HP EliteDisplay E272q) for this tripple monitor setup? The resolution of these displays that I want to work with, is 2560x1440p, and I will not be using my XPS screen with this setup. Could someone guide me towards what type of docking station I should get, or if this is even possible, given my current gear? Any suggestions are welcome!
