Required key not available

[b00f]

I compiled the driver and put it in /etc/modules to run after boot. but I got this error.

Failed to insert '8723de': Required key not available

How can I fix it?

[b00f]

I could fix it by disabling Secure Boot in UEFI (BIOS) settings. Is there any other way to fix it?
