Depends on just how far you want to take it.
There was a 'code of conduct amongst gentlemen' which lasted from the 17th century up to about WW2 in a lot of the British Empire - cheating at cards or finance, womanising or 'ruining a lady', cowardice, swearing and general bad behaviour (acting as a 'cad' or a 'bounder') could result in being cast out of 'polite society' and, in extreme cases, would require the offender to commit suicide (the 'gentlemanly' way out of trouble). This, of course, didn't apply to the 'lower classes' or to a gentleman's dealings with them (although a proper gentleman wasn't supposed to mix with the lower classes socially). It isn't exactly a chivalric code, but it would be an interesting concept to use in the Imperial nobility.
If you want an interesting chivalric code, try using Bushido - very much an idealised code of conduct covering general behaviour and fighting, and again, introduced late on in the Tokugawa period, after the Samurai had stopped widespread fighting amongst themselves and had a vested interest in staying alive as well as keeping the 'lower classes' in their place.
