ESP32-S3-WROOM-1 Flashing

[dodeca]

I'm designing a PCB which future plans of mass producing it in the hundreds. It contains an ESP32-S3-WROOM-1 module and other components that will be used to power LEDs. Due to space and cost optimizations having a usb port on every board that is only used once to flash then never again is not ideal. Are there any "flashing boards" that have a usb and only require a few pins or pin holes on the board I'm designing?

When looking at page 28 of the datasheet(https://www.espressif.com/sites/default ... eet_en.pdf) it seems like pins 35 and 37, along with VDD and GND, are the only connections I need to flash through UART?
