Norms disabling at explicit index creation using json template

Hi All,

I have explicit mapping template i.e .json template which can be execute at 1st of every month to log the records from application.some times I have observed that for all string fields in my template the "norms" tag is adding automatically with out defining in template.

"destination": {
"type": "string",
"norms": {
"enabled": false
}
},

when I did R & D around ,suggesting we need to disable norms at index template level.please explain me why this is adding automatically? can we restrict it using .yml configs or we need to prevent at index level itself?

Thanks
