[נפתר] Change main language

Background of the issue:
I wanted to change the main language of the website. I am considering redirecting the home page קישור נסתר to קישור נסתר or putting the main language (English) with another link like קישור נסתר. The goal is for the Portuguese language to appear first when people visit קישור נסתר.

Symptoms:
Potential issues with changing the main language of the website.

Questions:
Can I redirect the home page קישור נסתר to קישור נסתר?
Can I set the main language (English) to another link like קישור נסתר?
Will this solution ensure that the Portuguese language appears first when people visit קישור נסתר?
