Creation of App Service Managed Certificate via REST api restarts app service instance

Question

I am using the REST api to create a (free) managed cert and then add a hostname binding for the domain to my app service instance. This ends up restarting my app service.

Is there a way to avoid that restart?

This does not happen when I use the REST api to upload a PFX file with a cert - and the restart is not needed as the managed cert is not distributed to the CurrentUser\My store on the server nodes anyway.

When you add a hostname binding for a managed certificate to your Azure App Service, it often requires a restart of the underlying service to apply the certificate and hostnames correctly. This behavior is typically not seen when uploading a PFX file because the certificate is directly imported and applied without a restart.
