Possibility of restricting access to the project file via PLCnext Eng. by the roles

Hello colleagues,
There is a task to restrict third party access to the project using a password for the project file. Unfortunately, I didn’t find such information in plcnext.help
related question - is it possible to restrict access to project functions by role:
1. restrict access to opening the project file with a password
2. restrict viewing of the project file, but still retain the ability to load the project into the PLC
3. restrict access to individual project tabs.
If such opportunities exist, where can I read their descriptions?
