Disable F12 Developer Tools

F12 Developer tools has made my internet browser (all) unusable. Entering data is one key at a time interspersed with closing the DT. I have the Home Edition of Windows 10 and have all the updates, tried opening IE, going to gears and F12 DT is listed
but there is no way to UNCHECK it as was suggested in an earlier blog. Please tell me how to get rid of the F12 Developer tools or at least disable. I am writing this on my MAC because the F12 DT kept popping up when I tried to input this on my Windows 10
desktop. HELP

 

Cannot Disable Secure Boot

In BIOS, there is an option to disable/enable Secure Boot.

Whenever I disable it then go to boot windows, it tries and fails to boot about 5 times, then goes to a windows screen saying something along the lines of 'Cannot load windows, restart or troubleshoot'.

Troubleshooting does not work, nor does restarting.

When I switch from UEFI to Legacy in boot list options, it simply says that there was no OS detected.

Is there a tool or something that I can use to disable it instead?

TL;DR: Cannot Disable Secure Boot because if I do I cannot boot to windows.

 

disabling secure boot

Hello
These are the instructions I received from the engineers at Asus regarding disabling secure boot. I can do so by clearing keys but that is not advised. I want to use various Linux distros which require that secure boot be disabled. My new board is Asus Tuf z390 Gaming Plus Wifi.
Their directions below did not disable secure boot either. If you have any ideas I would appreciate them. The builder said he felt enabling CSM as Asus did should have disabled secure boot too.

>>BIOS -> Boot -> CSM (Compatibility Support Module) -> Launch CSM -> Enabled

1. Boot mode -> UEFI and Legacy
2. Boot from Network -> Legacy (old drives); or UEFI mode (for NVME/SSD drives)
3. Boot from Storage -> Legacy (old drives); or UEFI mode (for NVME/SSD drives)
4. Boot from PCIE/PCI -> Legacy (old drives); or UEFI mode (for NVME/SSD drives)
5. Go back to Boot -> Secure Boot -> OS Type -> Windows UEFI Mode (Windows 10/8.1/8) and Other OS (for Windows 7)<<
