High Temp PVA/ Dissolvable support?

Hello, I have an X1c using it for engineering work. Been using PETG, PAHT-CF (bambu labs), PA12-CF (Polymaker) & Bridge Nylon (Taulman). I had been using the PET Support which works pretty well now but due to some intricate features on the inside of parts we need / are looking at dissolvable support. I bought a roll of PVA from poly maker but immediately realized the temps are way off & am not going to be able to print. Has any one found a good High temp Dissolvable support? Looking for one that can print well around 290-300. TIA

Hello. Did you ever solve your problem? I bought S1 as well, but it says it works with Polymaker PA. After reading your post, I realize the printing temperatures are very different between the two, but I have yet to try it.
