Hi Helder,
Yes currently we don’t have roboto font installed on our theme. You can try some other font instead of Roboto font. If you like to use roboto then it needs code customziation.
Go to theme folder -> inc -> admin-> interface-themedefaults-value.php on line no 650 and add this below code
"Roboto" => "Roboto",
We always recommended you to create a child theme so that while updating to new version all your customized code will be lost. So better make a child theme and customize the code to be safe from updated version.
Thank you
