Adding a CD or USB drive to Optiplex 7090 Boot Menu

I'd like to add a CD/DVD drive or USB drive to my Optiplex 7090 boot menu.  I'm running Windows 10 Pro and BIOS 1.25.0.  I've read Dell article https://www.dell.com/support/kbdoc/en-us/article/lkbprint?ArticleNumber=000124391&AccessLevel=10&Lang=en but following those instructions fails because at step 6 the option for CD or USB device doesn't appear available to add.  I'm presuming it has been removed in some BIOS update since the article was published.  I'm getting the feeling that the evolution of Secure Boot has decided CD or USB boot capability is not to be allowed.  Being a retired desktop support tech I like to play with my machine.  It's not on a desk in the NSA... Is there no path forward for me in this situation?

it is a simple matter.  all you need is have a geunine bootable dvd and bootable USB that contains UEFI link like (such as MS installation media created by downloading from MS site).  Without a bootable dvd that contains UEFI link file, the dvd drive itself would not show in UEFI boot menu.  same story for USB boot device.  the concept of having device options show up in bios belongs to legacy bios only.  In UEFI, you ve got to have a UEFI boot link file present on a media already loaded in the drive before it could show up in boot menu.

@redxps630​ , thanks for the simple solution.  Contrary to Dell's documentation, no reconfiguration of the F12 boot menu is required as you say.  The boot media, whether CD, DVD or USB simply has to be inserted before booting to the F12 boot menu where it magically appears.
