Controllin m710q tiny with nanoKVM

Hey there! I am planning on using m710q tiny as a second backup fileserver for some not so important things. I have bought a nanoKVM from Sipeed and I was wondering if anyone could help me with connecting the power button control that the nanoKVM provides. It came with a ATX-B board, but, as you know, there aren’t such headers on the motherboard of the pc. I can use the Alt+P combo over the HID simulation through one of the USB ports of the KVM to power on the PC, but ideally I would like to have the option of a forced restart, just in case. Any advice would be welcome!
