Can you localize the area from which the sound is emanating? Is it inside the dashboard area? (My prime suspect…) or Is it coming from under the hood? or… ? ---

It might be a faulty HVAC door actuator that’s making the noise, especially if it seems to be coming from under the dashboard. One thing you got going for you, with knocking sounds it’s always better that it occurs with the engine off vs on. ---

Could also be ABS activating - the valves opening and closing or whatever it does. I get that in my 1999 Honda right after the engine starts. Sound seems to come from just in front of the firewall passenger side. That’s where the ABS unit with all the brake lines coming in and going out is. ---
