Yes, there are best practices to ensure a good immunity, meeting the class B CISPR 22 standard specifications and to keep the system safe and reliable. The recommendations that we have on the layout are laid out here when interfacing with the newly released ADE9178 metrology engine: https://wiki.analog.com/resources/eval/user-guides/ade9178#layout_information
There will be an "Architecting a Direct, 3-Phase Energy Meter with Shunts Using the ADE9112/ADE9113" application note accessible from the datasheet by end of 2024. It will go in details of the best way to reduce radiated emissions, choose the right decoupling capacitors, ground plane rules, and what performance to expect.
