Roman page numbering

[gsarrco]

I rendered the template and I saw that all pages of the book have roman numbering. While having it for the first pages of the book would be okay, for the whole thing it would not be very conventional. Scientific literature and also beyond use arabic numerals for the body of the works. Maybe it can be removed for the body of the book but kept for the introductory pages or remove altogether.

This is the tex line:
\pagenumbering{Roman}
