Hi,

The number you are looking for is what the SoftDevice calls "firmware_id" which is located in the 15th and 16th byte of the SoftDevice information structure:

To get this number you can use any software capable of reading out the flash of the device. Flash the SoftDevice to a nRF52840 and read out the value at address 0x300C by using any software you prefer. I recommend using "nrfjprog" which is part of "nrf command line tools" as shown in this screenshot:

For completeness, here is how you find the number in nRF Go Studio if it's of interest:
