_alias in mutation argument breaks compilation

I use client generation and we have _alias argument for one mutation in graphql schema I am using. This breaks compilation as generated MutationProjection method contains 2 arguments with the same name:

  public fun nodeSetCreate2(
    _alias: String? = default<MutationProjection, String?>("_alias"),
    summary: String? = default<MutationProjection, String?>("summary"),
    _alias: String? = null,
    _projection: MdNodeSetNodeMutationResultProjection.() -> MdNodeSetNodeMutationResultProjection,
  ): MutationProjection {
    field(_alias, "nodeSetCreate2", MdNodeSetNodeMutationResultProjection(inputValueSerializer),
        _projection, "_alias" to _alias, "summary" to summary)
    return this
  }

It generates this error:

e: file:///<path>/build/generated/sources/dgs-codegen/com/ataccama/metadata/client/dgs/client/MutationProjection.kt:3090:5 Conflicting declarations:
_alias: String? = ...
_alias: String? = ...

Would it be possible to override the parameter name somehow?

My current solution is to replace the name in the kotlin file right after it is generated. This is my current config of GenerateJavaTask:

tasks.withType<com.netflix.graphql.dgs.codegen.gradle.GenerateJavaTask> {
    schemaPaths = mutableListOf("$projectDir/src/main/resources/graphql-client/metadata/schema.graphqls")
    packageName = "com.ataccama.metadata.client.dgs"
    language = "kotlin"
    generateClient = true
    generateKotlinNullableClasses = true
    generateKotlinClosureProjections = true
    shortProjectionNames = true
    typeMapping = mutableMapOf(
        "AnyScalar" to "kotlin.Any",
        "BigDecimal" to "java.math.BigDecimal",
        "BigInteger" to "java.math.BigInteger",
        "Byte" to "kotlin.Byte",
        "Cursor" to "kotlin.String",
        "Duration" to "kotlin.String",
        "Filter" to "kotlin.String",
        "GID" to "kotlin.String",
        "Hcn" to "kotlin.Long",

        "ObjectLink" to "kotlin.String",
        "Patch" to "kotlin.Any",
        "RichText" to "kotlin.String",
        "SessionId" to "kotlin.String",
        "Short" to "kotlin.Short",
        "Timestamp" to "kotlin.String",
    )
    doLast {
        // Fix DGS codegen conflict: schema field `_alias` on nodeSetCreate2 clashes with codegen's own `_alias` parameter
        val mutationFile = file("build/generated/sources/dgs-codegen/com/ataccama/metadata/client/dgs/client/MutationProjection.kt")
        if (mutationFile.exists()) {
            var content = mutationFile.readText()
            content = content.replace(
                "    _alias: String? = default<MutationProjection, String?>(\"_alias\"),\n" +
                    "    summary: String? = default<MutationProjection, String?>(\"summary\"),\n" +
                    "    _alias: String? = null,",
                "    nodeSetAlias: String? = default<MutationProjection, String?>(\"_alias\"),\n" +
                    "    summary: String? = default<MutationProjection, String?>(\"summary\"),\n" +
                    "    _alias: String? = null,",
            )
            content = content.replace(
                "\"_alias\" to _alias, \"summary\" to summary)",
                "\"_alias\" to nodeSetAlias, \"summary\" to summary)",
            )
            mutationFile.writeText(content)
        }
    }
}
