Security Violation error after installing Security Update on High Sierra 10.13.6

Hi i installed macOS High Sierra on my Desktop and it booted, most of the things worked. But in order to install NVIDIA Web Drivers i had to update to get a supported build. So i downloaded the updates (security,safari,itunes) and installed it. It updated successfully but now when i try to boot into macOS i get a Security Violation error:

OCSB: No suitable signature - Security Violation OCB: Apple Secure Boot prohibits this boot entry, enforcing ! OCB: LoadImage failed - Security Violation

I appreciate any help, thanks in advance.

Hardware: - Ryzen 7 3700X - 32GB DDR4 3000 (Corsair Vengeance LPX) - MSI B450M MORTAR MAX - Samsung 960 Evo 500GB - GTX 1070 - Installation method: OpenCore
