The options that appear depend on what's available to the system (i.e., how the drive is partitioned, formatted and what OS is installed). If you have a drive that has a UEFI-bootable partition on it, it will show up as one of the boot options. If you don't, you'll get an error if you try to enable that option.
If you see multiple legacy boot options -- but not UEFI -- the drive is likely set up in MBR mode - not GPT mode (the former is the way to boot most Windows 7 and earlier OSes; the latter, for Windows 8 and 10). While Windows 7 can be installed in UEFI mode (64-bit only -- 32 bit cannot), most 7 installs are done in MBR/legacy mode.

Look in the Setup section of the owner's manual:
