Case insensitive when

Is it somehow possible to make when String comparison case insensitive by default?

when (subtype.toLowerCase()) {
    MessagingClient.RTC_SUBTYPE.sdp.toString().toLowerCase() -> onSDPMessageReceived(topic, sender, data!!)
    MessagingClient.RTC_SUBTYPE.bye.toString().toLowerCase() -> onRTCBYEMessageReceived(topic, sender)
    MessagingClient.RTC_SUBTYPE.negotiationOffer.toString().toLowerCase() -> onNegotiationOfferMessageReceived(sender, data!!)
}

This has too much repetetive code! Also note that MessagingClient.RTC_SUBTYPE is enum class and subtype on the first line is received from some client, so we must treat it accordingly.

var s1 =editText.text.toString()
var s2=textView_.text
var s3 =s1.equals(s2 ,true)

I would convert subtype to MessagingClient.RTC_SUBTYPE like so:

val subtypeEnum = MessagingClient.RTC_SUBTYPE.values().firstOrNull {
   it.name.equals(subtype, ignoreCase = true) 
} ?: throw IllegalArgumentException("${subtype} no value of MessagingClient.RTC_SUBTYPE match")

And then use it in when

when (subtypeEnm) {
    MessagingClient.RTC_SUBTYPE.sdp -> onSDPMessageReceived(topic, sender, data!!)
    MessagingClient.RTC_SUBTYPE.bye -> onRTCBYEMessageReceived(topic, sender)
    MessagingClient.RTC_SUBTYPE.negotiationOffer -> onNegotiationOfferMessageReceived(sender, data!!)
}
