Is it possible to apply specific Kotlin compiler arguments for an Android build variant ?
I can configure arguments with

tasks.withType<KotlinCompile>().configureEach {
  kotlinOptions {
    freeCompilerArgs = freeCompilerArgs + listOf(
      "-Xno-param-assertions",
      "-Xno-call-assertions",
      "-Xno-receiver-assertions"
    )
  }
}

but it's applied to all build variants, which is not what I want.
The kotlin.android Gradle plugin creates compilation tasks (compileDebugKotlin, compileReleaseUnitTestKotlin, etc) for each source set, but it seems there is no way to configure their kotlinOptions individually.

You can probably do a matching and filter by task name?

It works, but only from within afterEvaluate. It's because compile*Kotlin tasks are created lazily based on the created variants.
Because relying on afterEvaluate is flagged as a bad practice by Gradle, I'd expect the kotlin Android plugin to define an alternative configuration DSL.
Maybe it hasn't leveraged the new extension DSL introduced in Android gradle Plugin v7.0.0 ?

I have no idea about android.
But matching by name should not require afterEvaluate or you are doing something wrong.
Paul did probably not mean to use tasks.named("compileDebugKotlin") where that might be true, but more something like

tasks.withType<KotlinCompile>().matching { it.name == "compileDebugKotlin" }.configureEach {
  kotlinOptions {
    freeCompilerArgs = freeCompilerArgs + listOf(
      "-Xno-param-assertions",
      "-Xno-call-assertions",
      "-Xno-receiver-assertions"
    )
  }
}
