Dynamically changing supported languages

Thanks to both of you for your answer, however the solution proposed by aramiss is the fastest and simplest to set the value on the fly, for the moment I think I will adopt this solution.

But I also discovered another way to solve my request, CodeIgniter 4 Settings (https://github.com/codeigniter4/settings) , maybe it's even better because it allows me to save the data, maybe in the future I will use this also for other purposes.
