To erase flash, please use "Cy_Flash_EraseRow (uint32_t rowAddr)" API. It automatically configures the IPC structure (as explained in TRM) for you and initiates the flash row erase.

I check the following TRM, but the API does not hit in any TRM.
1) PSoC 63 with BLE Architecture Technical Reference Manual (TRM)
2) Registers Technical Reference Manual (TRM)
Maybe, there is no API information in the TRM.
Thanks and regards,
