Unable to remove the schedule option from Reports

Hi

We have built few custom BIP reports for Next gen HR Helpdesk and few of the reports should be accessed by Helpdesk Agents. However we donot want the agents to have the option to schedule the report.

Our custom agent role which a copy of the seeded helpdesk role do not have any such permission, neither we are able to remove the Schedule option from he permissions that we are putting at reports folder level.

Is this expected? If not how can this be achieved. Could anyone please help.

Many thanks
