My intel HD 630 integrated gcard can not detect 2nd monitor.

2nd monitor detected by nvidia gtx 1060 and driven by gtx 1060.

If i disable gtx 1060 on device manager, there is no way i get signal on 2nd monitor

Intel suggest it is Mobo problem, which hdmi output directly connected to nvidia gtx card. Is it true dell?

I dont want to enable my BOTH cards in order to use 2 monitor? It brings me awful battery performance.

Windows 10 is freshly installed (creators update) and drivers are up-to-date.
