[Koha] How can hide all MARC fields by default

Dear Friends, I would like to know, how can hide all MARC tags( from MARCBibliographic Framework) in one stretch ? My aim is create a blank frame work. Then enable (unhide) only necessary MARC fields from “Edit Subfield” section from MARC Bibliographic Framwork. Can I do this action using MySQL command? If so, I need your help to make a MySQL command for this purpose. -- Vimal Kumar V. Asst.
