Will turning on Secure Boot cause issues with an existing Windows installation?

[King Mustard]

Battlefield 6 requires Secure Boot to run but I have turned it off on my ASRock B650M Pro RS.

I cannot remember why I did this exactly, as it was a long time ago.

Will anything happen to my existing Windows installation if I turn on Secure Boot?

One simple answer ... NO!
