MikiBroki: Thank you very much for joining the Intel® Processors communities.
Based on the information provided above, you already ran the proper commands and it seems that everything is disable now.
However, you do have an OEM board that belongs to Gigabyte, and the board will still be vulnerable until Gigabyte releases a new BIOS version to fix this problem. So, the best thing to do will be to get in contact directly with them in order to get further details about this subject:
Any further questions, please let me know.
