Hello Krascovict and thank you for translating.

Note that I do not speak Portuguese.

Generally no, but you can look at the string in Weblate in other
languages like Spanish or French. See if they have translated it.
For example, if a variable name is defined with (define), in a few
cases, it is possible to translate it, but it must be translated
everywhere the same way.

Alternatively you would have to test in Guix if it works.

Regards,
Florian
