I think help article FAQ for BLE and Regulatory Certifications with EZ-BLE modules - KBA213976 answers most of your queries. Let me highlight them here again:
The module is designed to work with a standard 2.2 dBi dipole antenna. Any antenna of equivalent or less gain can be used without additional application and testing for FCC/IC regulations. The following table details approved antenna for the CYBLE-202007-01 module antennas.
Manufacturer Part Number Gain Antenova B4844-01 2.2 dBi RFlink RF21C01228A 2.0 dBi Pulse W1030 2.0 dBi
You do not need to redo the Bluetooth SIG certification with a new antenna as the RF-PHY test in Bluetooth SIG certification is not related to antenna gain.

This is the module evaluation board information.
The information I need is the schematic of Module (CYBT-333047-02), Block diagram, and BOM list.
For CYBT-333047-02, I would suggest you to contact your local Cypress team. We can follow this request in a SFDC case probably.
