Can Kopia be used as a portable binary in Windows?

How can one achieve a “portable installation” of Kopia and/or KopiaUI in Windows?

This would entail the following:

i) Installing/running the software does not require admin rights.
ii) Installation does nothing more than download the binary.
iii) Configuration file can be specified on command line.
iv) Paths in configuration file can be specified relative to current working directory.
v) Registry is not touched, nor the user’s AppData Local or Roaming folders used for caching or otherwise.

It looks like scoop installs kopia “in a portable way,” so I now just want to confirm that kopia will never create any files outside of “~/scoop” on windows when using scoop as installation method.
