Question About Programmatic Hot-Swap Control for DFR1168 USB4 to PCIe Dock

Hello everyone,

I am currently integrating the DFR1168 USB4 to PCIe docking station into a custom product and I am trying to control the hot-swap function from my own control board. After reading the available documentation, I am still a bit unsure about the correct setup for SW1 and SW2 when using forced startup mode.

My main question is about triggering a hot-swap event to the host system. Would temporarily disabling J3/J4 and then enabling them again be the correct way to simulate this behavior? If so, is there a recommended delay time that J3/J4 should remain disabled before turning them back on?

I am also wondering whether the board provides any dedicated header or signal that allows external control for this function. If not, is the only practical solution to remove J3/J4 and connect them to a custom control circuit on my PCB?

Any suggestions or experience with this setup would be very helpful. Thanks in advance!
