Hide Dashboard By Default

Hello,
Is there any possible script to hide the new dashboard of v13! I mean hiding Overview, Stats & Connections sections from Customer Doctype. v13-customer’s%20dashboard|690x404
as the below code is not working for v13:
cur_frm.dashboard.frm.fields[0].df.hidden=1;

Can use this - v13 onwards

To Hide Overview Section -
cur_frm.dashboard.links_area.collapse(true);

To Hide Connections Section -
cur_frm.dashboard.links_area.collapse(true);

If you remove argument-true, it will behave as toggle.
