In a few days I'm going to go stage 1 through Malone, and my EGR cooler hiss is growing louder and louder everyday, would the Dynamic EGR option which turns down the EGR after warmup fix this or do I need to block it off and completely delete it?

Yeah, if your EGR cooler is leaking at the changeover flap shaft, like they all end up doing on the BRMs, you'll still need a new cooler to accomplish what you stated.
If you are handy, you can remove the cooler, cut the shaft and flapper out of it completely, weld the end holes shut, reinstall it, and continue with your plan of dynamic tune. However, when you do that, you eliminate the full heat exchange ability of the cooler since that flap is no longer present and only half of the actual EGR flow will pass through it (the rest will just bypass). So it sort of diminishes the reason for having that sort of tune anyway.
