Hi JackDuhon,
Thanks for your post in Microsoft Community.
I'm Mosken, I do apologize for the inconvenience that you're experiencing right now, let me help you sort things out.
According to your description, I knew that the system prompts you to activate secure boot when you play a game after you upgrade win11, you see the entry of secure boot in the BIOS, but there is no option to activate. If my understanding is wrong, please correct me in the reply.
Under normal circumstances, you can focus the highlighted entry to "Safe Boot" in the BIOS, and then press Enter, a pop-up window will pop up containing "Enable", "Disable", etc. You can use the up and down keys to select, then Press Enter to confirm your choice, and finally, save your BIOS settings, and then restart the computer to see if it is normal.
If the above solution is not credible, please take a photo of this page in the BIOS and attach it to the next reply.
I wish the above will be helpful to you. Please feel free to let me know how it goes, and I will do my best to help you.
Best Regards,
Mosken - MSFT | Microsoft Community Support Specialist
