I think my car have the same issue, whenever i turn on the electronics of my car like headlights, AC or while turning the power steering as soon there is a loud knocking, cluttering sound appears, it's so annoying. Some mechanic told me that it is coming from Drive belt tensioner.
Bad Serpentine belt tensioner cause knock that perturbes Knock sensor and cause misfire.
This phenomen is generally observed in Hyundai Kia cars.

There is no way a serpentine tensioner will ever cause an engine miss. The timing belt tensioner yes, It will cause much damage in some cases.
If it’s not spinning your alternator fast enough then yea it will cause a misfire
Bad tensioner or idler pulley bearings can most definitely make the engine feel like it has an intermittent miss.
This video keeps showing timing belt but talking about a serpentine belt. Probably made by someone that doesn't actually work on cars.
