Custom board based on ESP32-S3-MINI-1-N8

Hi,
Designed a board based on the ESP32-S3-MINI-1-N8.
There is no board called ESP32-S3-MINI-1-N8 or ESP32-S3FN8.
Is it possible to skip the board definition and just select a MCU?

The closest board is the ESP32-S3-DEVKITC1-N8 but that one, as I understand it, do some special things with the GPIO used for the LED to get it blinking converting set/clear to neopixel serial data.

I do not want to go in and define my own board because that will break the possibility to upgrade the toolchains.
Thanks

The ESP32-S3-DevKitC is a good choice to start.
Then just make the necessary adjustments in the platformio.ini for the S3-Mini-1-N8
