Asus 97a usb 3.1 Bios written too?

[fuzzylogic]

I have recently installed High Sierra 

                                                  post install using clover and noticed that in the Tools section of my Asus Bios there appears to be a clover boot list even though there is no. usb drive installed. I have re flashed my Bios and notice that the files are still there they are clover config files, kext ect can anyone suggest a way to remove the files.

if this question is in the wrong section then can it be removed to the correct one

thanks

appreciate any help
