Is it possible to detect the cpu version, D or E?

Your question doesn't make sense, we don't have multiple CPU versions with those designators. There are different revisions of the silicon, but those are labeled ECO0 to ECO3.
Do you mean the differences between the ESP32-Wroom-32D and ESP32-Wroom-32E modules? If so, you can use these ECO numbers as a guideline. ESP32-Wroom32D does not have a specified ECO in it (it's likely to be an ECO1, but I can't guarantee there are none with a different ECO in it), but the -32E always has an ECO3 in it. You can find out the ECO at runtime using esp_chip_info() (in ESP-IDF at least)

esp_chip_info_t.revision seems to be right for me.
Thanks.
