The PC is on and my keyboard and mouse both light up however there is just no response or even prompt to enter the BIOS on the screen.

Hi ShowMeGirl1

To enable Secure Boot, your PC must have UEFI BIOS and you need to boot your PC into BIOS

Start your PC, on the manufacturers logo screen, there is generally an indication of how to boot your PC into Setup - usually it is F2, or F12 . .

On the Manufacturers Screen, repeatedly press that appropriate key, so your system boots into BIOS

If you do have UEFI, you will see the Secure Boot and legacy Boot options, turn off Legacy Boot (if applicable) and turn on Secure Boot

Also Please Note: to enable Secure Boot, your hard drive must be GPT, not MBR!
