I hope you are well today and thank you for your question.
Currently the theme doesn’t support it but we have added this as feature request which will be implemented in the future version of theme.
For now you have to either use plugin or develop custom code to display it.
Solution for this topic
Just want to update you here that WordPress by default provides Favicon option in Customizer Site Identity settings as shown in the attached screenshot so we don’t need to add separate theme option for it and you can just use this WordPress option.
