@ManojKumar may I ask why you are wanting to delete the status? I know you can look into the purging options to remove some of the data, but I'm not clear on what removing that status gives you.
Hi, I'm not sure precisely what you need but I'll provide you with various options:

In that case you would need a scheduled site workflow to iterate through each item (use this article - it's quite old but you should be able to apply the principle to your requirements). In the workflow you would need logic to check the value of the workflow status column and if that value equals 1 or 2 (see my previous reply) then use the Change Workflow Status to blank. This is highly inefficient though just to change these values.
My recommendation is to create a new column called Status in your list and hide the workflow status column from the view. As your workflow progresses, update the Status field with the values to want to represent the progress of the workflow.
