Hi @itsmifred,
Yes, you can translate the Cookie Banner with the String Translation feature in multi-language plugins such as PolyLang or WPML.
After saving the Cookie Banner settings once with one of these plugins enabled, the texts will become available for translation in those plugins.
Please refer to the below articles for further instructions, depending on the translation plugin that you use.
