Try this code:

B4X:

Private Sub SetReadonly
   TagTech.RunAsync("ReadOnly", "makeReadOnly", Null, 0)
   Wait For ReadOnly_RunAsync (Flag As Int, Success As Boolean, Result As Object)
   Log("Readonly: " & Success)
End Sub

Call it after writing was completed.

See makeReadOnly documentation: https://developer.android.com/reference/android/nfc/tech/Ndef.html#makeReadOnly()
