I want to put the subsection and the subsubsection in the text on uppercase, but I don't want to change the lowercase in the sumary.
My code is this:
\documentclass[a4paper, 12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[lmargin = 2.5cm, rmargin = 2.5cm, tmargin = 2.5cm, bmargin = 3cm ...

My code is this:

\documentclass[a4paper, 12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[lmargin = 2.5cm, rmargin = 2.5cm, tmargin = 2.5cm, bmargin = 3cm]{geometry}
\usepackage[english,brazil]{babel}
\usepackage ...
