是否可以在 Android 10+ 中格式化辅助 SD 卡？

Question

I'm writing an application that uses dedicated SD cards (usually 2-3) connected via a USB hub. The layout is as follows: SD cards -> USB hub -> Phone.

Is there any possibility to programmatically (Kotlin) format SD card (exFAT)?

Check this Code

fun wipingSdcard() {
    val deleteMatchingFile = File(Environment
            .getExternalStorageDirectory().toString())
    try {
        val filenames = deleteMatchingFile.listFiles()
        if (filenames != null && filenames!!.size > 0) {
            for (tempFile in filenames!!) {
                if (tempFile.isDirectory()) {
                    wipeDirectory(tempFile.toString())
                    tempFile.delete()
                } else {
                    tempFile.delete()
                }
            }
        } else {
            deleteMatchingFile.delete()
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }

}

private fun wipeDirectory(name: String) {
    val directoryFile = File(name)
    val filenames = directoryFile.listFiles()
    if (filenames != null && filenames!!.size > 0) {
        for (tempFile in filenames!!) {
            if (tempFile.isDirectory()) {
                wipeDirectory(tempFile.toString())
                tempFile.delete()
            } else {
                tempFile.delete()
            }
        }
    } else {
        directoryFile.delete()
    }
}
