how to restrict access to the WebUI and API by source IP

Hi,
I'm looking for a way to filter WebUI by source IP on Satellite 6.15.
I'm found technote for satellite 5.X but not for 6.X

Otherwise if I have two networks interfaces, I can have the satellite web console answer only on one interface.

Regards,
