I started House of the Dragon last week and wanted to turn it off immediately when Matt Smith jousted while wearing a helm with no visor.

This happened though. I know of at least 1 spanish knight in the 1450s who did it, according to a bourgundian chronist. He was put out there as a negative example though. AFAIK it is speculated that turney-culture in the late middleages had a subgroup of participants that wanted to show prowess by participating severly under-armored compared to their peers. We are talking about opting out of jousting sets (add on armor) and some even having breastplates with big holes in them or (as stated) not wearing a visored helmet. Considering the abundance of special turney-armor and add-on kits at the same time though it seems clear that the under-armored guys were some kind of show-off/wannabe minority.
