No, no , there should be an option on the BIOS to disable but if there isn't one, then no problem. A module can be blocklisted but no need.
The question was about being sure. If you are sure you don't have a cable plugged in thinking that is on another, all is good - for this exercise-.

It does smell a lot like some hardware problem. Which hardware is the not obvious part.
