Disable Automatic Issuer Configuration in the Appsync OpenID Connect Authorization mode

In the Appsync OpenID Connect authorization mode. Appsync automatically adds a .well-known/opened-configuration path to the provided Issuer URL. This is causing a huge problem because my application uses custom keys to generate the Azure AD OAuth JWT ID token. My OIDC meta document path is like this: 'https://login.microsoftonline.com/{tenant_id}/.well-known/opened-configuration?appid={client_id}'(i.e., has a query parameter at the end) which contains the jwks_uri(This jwks_uri contains the public keys of the created JWT id token). As you can see, in my case, a query parameter(?appid={client_id} was added at the end of .well-known/openid-configuration. So is there a way to Disable Automatic Issuer Configuration at the Appsync level so that I can stop .well-known/openid-configuration to be added and i can add my metadata document URL provided above directly in the Issuer URL?
