Indeed it is pretty easy to build avrdude under Linux.

avrdude 7.1 was released early this year.

But if you are reluctant to build from source, Arduino project provides
a static link version here for Linux/macOS/Windows.

Interestingly we have similar discussions here.

Either jtag2updi or SerialUPDI can work well with the new UPDI AVR parts.

jtag2updi: you can use a Uno or Nano to make a UPDI programmer.

SerialUPDI (the URL name has jtag2updi but it is really talking about
you can use a USB to TTL converter to make a UPDI programmer
