Hi,
1. You can install the plugin, translate the strings, generate the .mo files, and you can deactivate the plugin, it won’t create any issues in that way.
OR
2. You can manually translate the strings using POEdit, or some of the tools noted in the codex, https://make.wordpress.org/polyglots/handbook/tools/other-translation-tools/
Let us know,
Thanks,
laranz.
