Multitenant version 13 multiple domain ssl

I know this is more of certbot issues but I believe it related to erpnext
I have 2 domain and 3 instance of site: erp. backoffice, com
Site1.portal frontoffice, com
Site1.event event.backoffice,com
Please how do I install certbot for all domain on same vps without affecting others
Anyone has a similar solution to point me to thanks.
