Hi, thank you again for your answer.
I have an idea that would be the best for my situation, I want to ask you what do you think about it.
Because I have not done any change to the core files of the GeneratePress Original Parent theme, I will keep using it, and if a day comes when I want to do changes to the core files I can make my own child theme based on the GP Original Parent theme and start doing my own customisation on the child theme I’ve just created.
Does it make sense? Sorry if the question is to dumb, I’m just learning.
Thank you.
