Hi @ednieuw. Is there a specific reason you want to use 2.0.17?
If you do need to use a 2.x version of the platform, I recommend using version 2.0.18-arduino.5 of the "Arduino ESP32 Boards" platform. This version is very similar to version 2.0.17, but with some small Nano ESP32-related things Arduino backported from the 3.x version series.
Excellent idea to check what changed in the board definition between the two versions!
However, you must have made that change. The values of those properties were false even in 2.0.17:
There were no changes to the board definition between the two versions.
