How to give read and write rights on a specific field on a form

Hello,
Is it possible to assign read ond write rights on a specific fied in a form? For example, The GM of this company would like to have the exclusive right of assigning tags to clients in the system! How to go about it please?
Kind regards

Hi,

Not possible with the core.
Should be possible with external module like https://www.dolistore.com/en/modules/469-myField---personalization-of-fields-and-of-their-access.html

Thank so much. i do appreciate!
