The workaround I found so far is to use project.afterEvaluate {} to access the build types, as they are created only after Baseline Profile Gradle Plugin creates them:

Kotlin

android {
    buildTypes {
        release { ... }
        project.afterEvaluate {
            getByName("benchmarkRelease") { }
            getByName("nonMinifiedRelease") { }
        }
    }
}

Groovy

android {
    buildTypes {
        release { ... }
        project.afterEvaluate {
            benchmarkRelease { }
            nonMinifiedRelease { }
        }
    }
}

This way there are no redundant build variants created.

Attaching a sample project for convenience.
