How can I write in gradle.kts to enable the K2 compiler only when doing a debug build?

@Kensuke Sano,
I have found the following method:
1. In build.gradle.kts script define a new variable, like:

val isDebugBuild by extra { project.findProperty("isDebugBuild")?.toString()?.toBoolean() ?: false }

2. Add a condition with selection of language version:

kotlin {
    sourceSets.all {
        languageSettings {
            if (isDebugBuild) {
                languageVersion = "2.0"
            } else {
                languageVersion = "1.9"
            }
        }
    }
}

3. When run gradle build command: specify this variable as true:

./gradlew build -PisDebugBuild=true

If I understood your request incompletely, can you please provide more details and conditions regarding the situation?
