So I am one of many that have trouble connecting to wi-fi after installing Ubuntu to dual boot with my Windows 10. I have followed everything in this guide, Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE)
and the only thing that is holding me back is not being able to disable secure boot. In my BIOS, there is nothing labeled "secure boot." I did fast boot but that didn't change anything, any recommendations?
This is the link to 5 pictures in each tab of my BIOS if anyone can tell me what I should disable:
