STM32CubeProgrammer Option bytes settings

I am using the latest version of the STM32CubeProgrammer (v2.16.0) and am connected to a STM32F405RGT6 via an ST-LINK/V2.

The problem is finding the nBoot0 and nBoot1 settings under the Option bytes tab in the software. Does anyone know where I can find this? I have seen other people having these settings under the User configuration but I dont seem to have does. See image.

Hello @mathieusteketee 

As you can see on the RM0090, In the STM32F4xx, three different boot modes can be selected through the BOOT1 and BOOT0 pins. only There is not any Boot bit:

Here are all available option bytes on the STM32F405:

Thank you for reply @STTwo-32

I see, the only settings available for the STM32F405 are the ones I orginally had. 

Is was thinking of using Pattern 1 as desribed in the AN2606:

And then setting Boo0 = 1 and Boot1 = 0:

What is the alternative if I dont have access to nBoot0 and nBoot1?
