Not an official one -- the pyboard (all variants) is supported by mboot, but that's a dfu bootloader not uf2.

However, if you want uf2 on the pyboard you could use Adafruit's tinyuf2 -- see https://github.com/adafruit/tinyuf2/

However you'll need to add a board definition for the pyboard. It's an stm32f405, so you should be able to adapt the feather_stm32f405_express definition here. https://github.com/adafruit/tinyuf2/tre ... 2f4/boards

Note that when you compile MicroPython firmware (if that's your goal) for a uf2 bootloader, you'll need to configure the linker script. See how that works for mboot (via the USE_MBOOT makefile argument).
