A quick online check showed that your CPU has Intel HD Graphics 530. The motherboard has the output ports for on-CPU graphics.

I don't own Intel, but it seems if you simply remove the GPU and use the video output port on the motherboard, it should boot up.

I do know on my AMD MBs, one can turn off the CPU graphics in BIOS, if on-CPU graphics exist. Can't say if your MB has on-CPU graphics disabled. But, I imagine they are not disabled.

Just speculations for what they are worth.
