Updating ESP32 firmware from another ESP32 over USB, similar to how esptool.py works

Is there a way to update the firmware on one ESP32 from another ESP32 over USB, similar to how firmware can be updated using esptool.py?

This would essentially be like a port of whatever magic esptool.py uses over USB to update an ESP32, but instead of running through Python it would be an Arduino C++ sketch and would read the firmware to write to the other ESP32 from SPIFFS.

How to Tag

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.

complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
favor using existing popular tags
read the descriptions that appear below the tag

If your question is primarily about a topic for which you can't find a tag:

combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
