Disable license/copyright in footer?

[zeisss]

I was just playing around with your tech docs template (to check if this might be of interest for my private projects) and noticed the footer with the hardcoded license / crown copyright.

Is it possible to add a flag similar to show_govuk_logo to disable / overwrite this?

(I also tried creating my own source/layouts/_footer.erb but that didn't seem to do the trick. )
