How can I disable Mobile Time Entry for one Payroll Manager while keeping Manage Timesheets permissions?

If you mean the Manage my timesheets permission for your Payroll Manager, enabling this option will automatically select the Mobile time entry checkbox. This setting cannot be customized, as it is intended system behavior.
 

If you’re referring to Manage timesheets for all team members, you can achieve this by changing the employee’s permissions. Only account administrators and managers can modify team member permissions. Before making changes, confirm that your account-wide settings allow for individual permission overrides.

Here’s how:
 

1. Go to Company Settings, then Time Options.
2. Select Time Entry.
3. Uncheck Allow team members to manage their own timesheets and Allow team members to track time on the mobile app.
4. Hit Save.

Then, for that specific Payroll Manager:
 

1. Go to My Team and open their profile.
2. Select the Permissions tab.
3. Tick the Manage timesheets for all team members checkbox.
4. Make sure Mobile time entry is unchecked.
5. Click Save.
