Disable playing joining announcement or make it configurable when inviting PSTN number to group call

An azure bot creates an outbound call to a teams user/client.
The call is answered and connected.
The bot invites a PSTN destination into the same call which will convert the call into a group call once the PSTN destination answers the call. The graph API that is used for inviting PSTN user to group call: https://learn.microsoft.com/en-us/graph/api/participant-invite?view=graph-rest-beta&tabs=http.
When the PSTN user answers the call, an announcement is played to prompt the PSTN user to press 1 to join.
Once the PSTN user press 1, another announcement is played to indicate “joining group call”.

Our solution is a contact center solution. We use the group call to host a queue call so it is not considered as a meeting/group call. We need a method to make disabling the announcements programmable: either a policy that can be applied to the app id which is created for our solution that is built on Graph API or make it configurable via Graph API.
