Is it safe to disable Secure Boot for Linux testing and re-enable it later?

Hey everyone! I'm trying to run some hardware tests on my ASUS Strix laptop using Linux, but I can't boot when I have a USB with a different bootable partition. So, I think I'll need to disable Secure Boot. However, I'm seeing that my UEFI will warn me that everything related to Secure Boot will reset back to factory defaults.
Here's my plan: I want to disable Secure Boot to do my testing—I plan to make a full disk dump of my Windows installation first. Once I'm done with my tests, I want to restore my Windows image and then re-enable Secure Boot. Do you think my Windows will work fine afterward? I'm particularly concerned about gaming support (like Riot Games) that needs Secure Boot enabled. Anyone know if this is a safe process? Thanks for your help!

When you disable Secure Boot, it won’t reinstall your Windows. Just keep in mind that some setups might have issues with Secure Boot keys being reset. If you’re planning to restore your Windows image after Linux testing, you should be fine, but make sure to backup everything first just in case! If you keep everything organized, you should be able to get back to normal without any hassle.

You could also consider using a Linux distro that is secure boot compatible and recognized by Microsoft. This way, you might not even need to disable Secure Boot. But if you do go for a distro like CachyOS, just be aware that you might need to add the Secure Boot keys manually.
TechieB33: I attempted to add the Ventoy cert in UEFI, but it didn’t seem to work right. CachyOS isn’t Microsoft approved, so I’m hoping to get it up and running regardless. Do you think it'll be tricky with Secure Boot?

I’ve switched Secure Boot on and off a few times and never faced issues. For Ubuntu, it typically doesn’t require disabling Secure Boot at all, so you might want to consider that option if you haven’t already.
TechieB33: Yeah, I’m hoping that once I re-enable Secure Boot, my Windows installation will register back to UEFI and work just like before. Do you think that's how it should go?
