Create App Service Managed Certificate with FrontDoor CNAME

I have a linux Web App backend attached to a FrontDoor instance with a custom domain, but I'm unable to create a managed certificate on the web app due to the error: "Hostname not eligible for App Service Managed Certificates creation."

How do I complete this step if the CNAME record is pointing to FrontDoor? I cannot temporarily change the CNAME record as it's a production website. Adding a "awverify" TXT record works for adding the custom domain to the web app, but not the certificate creation.

Unfortunately it does not seem this is possible.

this is from another thread i found here: https://serverfault.com/questions/997025/hostname-not-eligible-for-app-service-managed-certificates-creation

App Service Managed Certificates can only be used with URL's that are setup as DNS CNAME records. "www.stratus-integration.com" has been setup as an A record, not CNAME. You will need to delete the A record and create a CNAME record pointing to the app service DNS name.

Is there a possibility you can create the cert elsewhere and just use a regular SSL Cert?
