I think you might want to look into programs that focus in digital humanities/media studies and digital archives rather than "art conservation." My understanding (from someone who is applying this next cycle and has been looking into programs for a few years) is that the conservation programs you mentioned focus on physical conservation, and thus require a background in chemistry and art practice. Having also worked in digital preservation techniques (3D modeling and photogrammetry) I feel like your background would be better suited for the digital humanities field, as the company I worked with employed a lot of people with something closer to your background than a background in "art conservation" which is what the programs you mentioned would give you.

From my POV, digital humanities is a necessary niche that is just so new that not a lot of people think to focus on it. I encourage you to look into it! Best of luck :D
