Curiosity nano debugger

In the Microchip curiosity nano documentation it states:

4.1.1 Debugger
The on-board debugger on the AVR128DB48 Curiosity Nano Board appears as a Human Interface Device (HID) on the host computer’s USB subsystem. The debugger supports full-featured programming and debugging of theAVR128DB48 using both MPLAB® X IDE and Atmel Studio 7, as well as some third-party IDEs.

in particular I am interested in the bit where it states “as well as some third-party IDEs.” and my question is : Is PIO one of those third-party IDEs.?

This is really a follow on question from others where I’ve asked about debug options for an avr4809.
