DNS based validation for custom domain automatic renewal prevents using external WAF vendor

Alike the Azure App Service, when you configure a Custom Domain on Azure Static Web App you need to validate it by setting up a TXT DNS record and then mapping the domain with A and CNAME DNS records.

If you need to use an external WAF vendor, you need to change those A and CNAME DNS records to the WAF server, which will connect to the Static Web App as backend.

But unlike App Service, which does not revalidate Custom Domains, Azure Static App does it, after 6 months Azure will revalidate the Custom Domain and as the A and CNAME records are not mapped to Azure anymore, it will fail and invalidate the Custom Domain.

Is there a way to turn off the automatic Custom Domain renewal/revalidation, in order to keep it always valid for use with an external WAF vendor?
