Okay, cool.
I have created a board file for the ESP32-S3-FH4R2 in my pio-boards repository.
This should make it easier to use in the future.
Create a file C:\Users\<username>\.platformio\boards\esp32-s3-fh4r2.json.
Copy the content of esp32-s3-fh4r2.json into the file.
Use the following for the platformio.ini
[env:esp32-s3-fh4r2]
platform = espressif32
framework = arduino
board = esp32-s3-fh4r2
Let me know if this works for you.
