Subpanel ground rod requirement
Starting from the 2008 National Electric Code, subpanels must be wired with a four-wire feed: two hots, one ground, and one neutral wire. The grounds and neutrals must be isolated.

Understanding Ground Rod Requirements for Sub Panels: What You
The answer to whether you need a ground rod for a sub panel largely depends on the specific circumstances of your installation, as well as local electrical codes.
Bonding and Grounding, based on the 2020 NEC
You need a 1/0 AWG supply-side bonding jumper for each raceway [250.102 (C) (2) and Table 250.102 (C) (1)]. A single supply-side bonding jumper is permitted for multiple raceways based on the
Why are Neutral and Ground Wires Separated in a Subpanel?
According to NEC Article 250, neutral and ground wires must remain separate in subpanels. Bonding (connecting) the neutral and ground should only occur in the main panel or at the first service
Grounding requirements for main panel and subpanel
If an additional ground is installed then a minimum of 6'' spacing is required between them. The only time the neutrals and grounds are allowed to tie together are in the main disconnect.
