Hello K2STG-Lakshmi,
Did you find an answer to your question?
All of the form links are completed via K2 for SharePoint app: https://help.k2.com/onlinehelp/K2ForSharePoint/ICG/4.6.11/default.htm#Install_Topics/OnPrem/Add_App.htm
If you go with the default form generation from K2 for SharePoint, it will generate separate display/new/edit views and forms. So changing one will not impact the others. You would need to develop a single view that can be used in multiple forms and with the rules to handle all three modes. K2 for SharePoint will not do this for you. What may help when creating the single view is that you can refer to the design of display/new/edit views that K2 for SharePoint to help understand all that needs to be done to get a working single view that can replace the three.
