JSON Schema - How to narrow down possible array object values - jsonschema

Question

How can the following requirements be configured in a JSON schema.
I have the following JSON
{
"orderMethods": [
{
"requestType": "some service",
"deployType": "MANUAL",
"deployLabel": "some label"
},
{
"requestType": "some service",
"deployType": "MANUAL",
"deployLabel": "some label"
},
{
"requestType": "some service",
"deployType": "AUTO",
"deploySubType": "REST",
"deployLabel": "some label",
"deployConfig": "some config"
},
{
"requestType": "some service",
"deployType": "AUTO",
"deploySubType": "DB",
"deployLabel": "some label",
"deployConfig": "some config"
}
]
}
Requirements:
only one deployType = "MANUAL" is allowed
only one deployType = "AUTO" is allowed
additionally, only one deploySubType = "REST or "DB" is allowed
Currently I have the following JSON schema. Unfortunately the above JSON is valid. How can the above requirements be addressed?
{
"$schema": "http://json-schema.org/draft-07/schema",

"properties": {
"orderMethods": {

{

},
"additionalProperties": false,

]
},
"OrderMethodAutoDBDeploy": {
"type": "object",
"properties": {
"requestType": {
"type": "string"
},
"deployType": {
"const": "AUTO"
},
"deploySubType": {
"const": "DB"
},
"deployConfig": {
"type": "string"
},
"deployLabel": {

}
},
"additionalProperties": false,
"required": [
"requestType",
"deployType",
"deploySubType",
"deployLabel",

]
}
}
}
Thanks for your help/ideas.
