Cloud formation template modifications management

Hi, I have an amplify app. I added custom resources with a CloudFormation template. This template add a webACL from the WAF, add some rules, create some IPset, a Loggin group and associate this webACL with some resources. My problem is that when i modify the rules the amplify push fail because the association already exist on my resources. The modification of the ipset do not matter the amplify push accept it but the modification of WebACL cause the association creation to be triggered again and as it already exists, the "push" to fail. Is there a solution ? How do i manage those rules modifications in a IAC way ?
