3 monitors on NitroPC

I’m considering buying the nitropc.

In my current setup I have an HP Z600 workstation connected to 3 HP 27" 16:10 monitors. All the monitors have DP, VGA and HDMI ports.

Is there a way to connect and configure my 3 monitors on a nitropc running Qubes?

An alternative solution could be to add an e-gpu box and fit in my current graphic card but I don’t know if (any or a specific) e-gpu can work with a nitropc running Qubes.
Anyone who tried such a solution (e-gpu)?
