You have no worries my friend.
You can omit the blue wire if you want

Thank you. What is the best way to “omit” that wire if I wanted it I put the smaller pin plug on that cable?

You can clip the blue neutral wire off, and forget it exists, it is not necessary.
Or
You can leave it as it is- it is not doing anything right now anyway .
Just avoid connecting any wires to it
