I guess the big question is why do you need stiffer suspension/springs ?? , if you are quite a bit above the target weight for the bike , you are limited .... I know that for the most part springs are unavailable for it , but that does not mean companies like BBR or some other company wouldn't offer higher rate springs , and your only option is to literally call around (or email) the suspension companies like Factory Connection , BBR , etc. , I do know that Race Tech does not offer springs , but they may have some other "workaround" to help with your needs depending on the limitations ........ You "can" stiffen most bikes with valving changes , but that bike has basically no "valving" to speak of , and is basically springs and oil for the most part ..... You could attempt a slight workaround , by using heavier viscosity fork oil , so instead of lets say 5 weight , you could replace it with 10 or 15 weight , though that is not really a fix , it may be a band aid that might make the ride more pleasant ....
What do you weigh ?? , and what are your specific needs/concerns with the stock suspension ?? , what are you doing with the bike that is causing the need for stiffer suspension ?? , or is it a physical (you) weight issue that puts you outside of the target weight as a rider for that bike ??
You "may" have to switch to a bike more accommodating to your needs , sometimes that is the best option , but more info is needed to really give you any suggestions/options other than what I have explained so far
