Apparently not.
If you followed the instructions, you have installed Katapult first and you have chosen Bootloader offset (16KiB bootloader) during the configuration of Klipper. In this case no .uf2 is built and it is not needed as you have Katapult.
Further, the instructions clearly tell you how to flash Klipper.
If you do not use Katapult (which strictly speaking is not needed for this board) then you must chose Bootloader offset (No bootloader) and then a .uf2 is created that you can either:
- Copy to the mounted
.uf2partition as described, e.g. in Raspberry Pi Pico + ADXL345: Portable resonance measurement - Flash with
sudo make flash FLASH_DEVICE=2e8a:0003
