Change Account form Header Title value

Hi,

I want to change account form header value only in display. In header title account primary attribute value is display that is name. But I want to display other custom attribute value.

We are using CRM 2016, I know there is a method available for access header fields Xrm.Page.setControl("header_name"). But this update name attribute in record that I don't want. I want to update only in display.

please help me.

Thanks,
