Is there a command that shuts off power to both USB 2.0 ports on the Pi 4?

Bonus points if the command does not disable the USB 3.0 or Ethernet.

It seems that this could be the solution for individually on/off control: raspberrypi.stackexchange.com/a/49442/111436 and this: raspberrypi.stackexchange.com/a/8652/111436 for on/off for the USB hub. Both solutions worked on previous Pis so might be possible that they still work for the Pi 4.

Is Ethernet still tied to USB in the pi 4 like in earlier pi's?

According to (raspberrypi.org/forums/viewtopic.php?p=813383), sudo ./hub-ctrl -h 0 -P 2 -p 0 ; sleep 3; sudo ./hub-ctrl -h 0 -P 2 -p 1 should turn off USB power, wait three seconds, and turn it on again, without harming ethernet -- however, it was tested on a Raspberry Pi 2B.
