Hi André,
For the mentioend use case, you just need to set the locale in the AdvanceOptions property as shown below.
"locale: 'pt-br'"
Final JSON ConfigOptions value:
"header: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek'
},
theme: false,
firstDay: 0,
isRTL: false,
height: 'auto',
contentHeight:'auto',
aspectRatio:'2',
eventLimit:'True',
defaultView:'dayGridMonth',
allDayText:'all-day',
axisFormat:'h(:mm)a',
slotDuration:'00:30:00',
snapDuration:'00:30:00',
scrollTime:'06:00:00',
minTime:'00:00:00',
maxTime:'24:00:00',
slotEventOverlap:true,
selectable:true,
selectHelper: true,
allDayDefault:false,
editable:true,
locale: 'pt-br'"
See this demo screen: FullCalendar_Locale_Change

I hope this helps you!
