How to enable DriverKit-specific entitlements checks

Question

Run the command below can disable DriverKit-specific entitlement checks in macOS. I learned this from PCIE DriverKit cannot be loaded correctly due to entitlements issues.

sudo nvram boot-args="dk=0x8001"

How can I enable the DriverKit-specific entitlement checks again? Thanks a lot in advance.

Answer 1

If you have no other boot-args, this should do it:

sudo nvram -d boot-args

Otherwise, just run sudo nvram boot-args="<blah>" without the dk=0x8001 part.

Note that you do NOT want to use dk=0x0 as this turns off DriverKit altogether!
