Hello @Dhaval Shirsath ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand that you would like to know if you can have separate WAF policies for each frontend domain on Front Door.
Yes, if you have multiple custom domains, you can use separate WAF policies for each domain.
As long as it is a different FQDN, you should be able to associate a different WAF policy.
Kindly let us know if the above helps or you need further assistance on this issue.
Please "Accept the answer" if the information helped you. This will help us and others in the community as well.
