How to disable _all field in production mode?

[majid_zarrin]

Hello
I had Elasticsearh v5.6.2 and I do upgrade to v6.0.1.
I expected Elasticsearch removes _all field because I didn't explicitly declare it as true on the mapping but it didn't.
Is there any way that I disable _all field in production mode?
thank you.

Thank you @warkolm,
I tried that before but I got an error on disabling _all .

#1 try
PUT /users/_mapping/messages
{
"_all": {
"enabled": false
}
}
#1 response
{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "mapper [_all] enabled is true now encountering false"
}
],
"type": "illegal_argument_exception",
"reason": "mapper [_all] enabled is true now encountering false"
},
"status": 400
}
#2 try
PUT /users
{
"mapping": {
"messages": {
"_all": {
"enabled": false
}
}
}
}

I have the same issue. I'm trying to disable _all to update to ES 6.1 but i get this error:

{"type":"illegal_argument_exception","reason":"mapper [_all] enabled is true now encountering false"}

You don't need to enable or disable it anymore. It's not a field anymore but a feature.
