Hi EGPUler!

I have an old Dell XPS17 L702x which i want to use for mining purposes. My Laptop has an internal Geforce GT555M Graphicscard, igpu is disabled on a hardwarelevel (bc of 3D screen) My Laptop also has 2 minipcie Slots. It is possible to attach two different Nvidia Graphicscard and use both for mining? Anybody tried this or has an answer? 
Thanks guys!!

I tried connecting 2 eGPUs via TB3 ports to my Mac Mini, and they were both identified and working in macOS Catalina, however, not sure regarding Windows / Windows laptop / other connections. Might be that each specific case is different as well and depends on many factors.

@susurs, Multiple eGPUs running on one host is possible in macOS, Windows, and Linux. The crucial component/s is the connection interfaces available through each machine. The Mac mini for example can host 4 eGPUs in macOS through Thunderbolt 3 ports. An Alienware 13R3 can handle 3 eGPUs through AGA port, TB3 port, and M.2 socket. You may be able to run two mPCIe adapters on your XPS17 L702x.

Thanks guys. Also will the mining hashrate be lowered if i connect a RTX 3090 via mini pcie? I mean its not the same as gaming right? I read in a nividia forum that nividia blocked riser usage and with it also minipcie usage on the RTX 3090, but i couldnt find any actual information on it. I don't want to connect any screen to the GTX 3090. Anyone tried that? I want to use the RTX 3090 on the minipcie only for mining while i do actual graphics / video work on the GTX 1060 where i connect my display.
