what's the correct way to write a

ignoreFunction

for

SpreadOperator

here instead of using the annotation?

package com.example.demo

import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
import org.springframework.scheduling.annotation.EnableAsync

@EnableAsync
@SpringBootApplication
class DemoApplication

fun main(args: Array<String>) {
    @Suppress("SpreadOperator")
    runApplication<DemoApplication>(*args)
}

You should target main. So

com.example.demo.main

should work.
