Direct Keil to use specific board

[SergeyP]

I have 1 dongle and 2 NRF52DKs attached to my computer at the same time, when I am trying to use Keil to program just 1 board it seems like attempts to access all 3 my boards. Is there a way to tell Keil which exactly board (USB port# ?) I want it to access?

This is the screen I am seeing once I click the button "Load" and it appears for as many times as many "not intended for programming" devices I have attached to my computer:

Hi,

When more than one nRF device is connected to your PC, you will need to selected what debugger you want Keil to use. If you have not selected what debugger you want to use, you will get the error "No JLink is selected":

If you click on the "Options for Target" button, , and click on the debug tab, you will get this menu:

If you click on the "Settings" to the right, you will get this menu:

In the SN(SerialNumber)-dropdown menu, all the available debuggers will be listed. Select the serial-number for the debugger you want to use in the menu, and click "OK".

Thanks for the details, I have done that but I am still seeing the same message as I saw earlier (I just updated my original question with that screenshot) which asks me whether I want to update those "other" attached boards which I don't want to be touched at all so I have to always answer "No" and I found it annoying.
